JavaScript and TypeScript are two of the most important skills for modern web development. If you are planning to start a career in web development or want to improve your chances of getting hired, you may wonder which one employers actually want.
JavaScript has been used for many years and remains one of the main languages behind websites and web applications. TypeScript is newer and builds on JavaScript by adding features that can make large projects easier to manage. Many companies now use both, which means learning TypeScript does not replace the need to understand JavaScript.
The good news is that you do not necessarily have to choose only one. Understanding JavaScript first and then learning TypeScript can give you a strong foundation for many developer jobs.
Why JavaScript Still Matters to Employers
JavaScript remains a major requirement for web development jobs because it is used across almost every part of modern web applications. It can make web pages interactive, handle user actions, communicate with servers and help create complete applications.
Employers value JavaScript because it has been around for a long time and has a large developer community. There are also many tools and frameworks built around it. A company may have an existing JavaScript application that needs regular updates, bug fixes and new features. Developers who understand JavaScript can work with these projects without having to learn an entirely different language.
JavaScript is also important because many popular development tools are closely connected to it. A developer may work with React, Vue, Angular, Node.js or another JavaScript-based tool during their career. While each tool has its own way of working, a solid understanding of JavaScript makes learning them much easier.
For someone looking for their first developer job, JavaScript is therefore a skill that should not be skipped.
Why Companies Are Adopting TypeScript
TypeScript has become popular because many web applications have grown much larger and more complicated than they were in the past. When a project contains thousands or millions of lines of code, small mistakes can become difficult to find.
TypeScript helps developers catch many common mistakes while they are writing code instead of discovering them later when the application is running. It also makes it easier for developers to understand what different parts of a project are expected to do.
This can be particularly helpful when several developers work on the same application. One developer may create a piece of code that another developer needs to use weeks or months later. TypeScript can provide clearer information about the data that code expects and returns.
Because of these benefits, many businesses have started using TypeScript for new projects and gradually moving older JavaScript projects toward it.
JavaScript Is the Foundation for TypeScript
One of the most important things to understand is that TypeScript does not replace JavaScript. TypeScript is built on top of JavaScript.
This means a developer who wants to become good at TypeScript should understand JavaScript first. Concepts such as variables, functions, objects, arrays, loops, conditions and browser events are important in both.
For example, if you do not understand how JavaScript functions work, simply learning TypeScript’s additional features will not make you a strong developer. You may be able to write code that looks correct, but you could still struggle when something goes wrong.
Employers generally want developers who can understand the language underneath the tools they use. This is why JavaScript knowledge continues to matter even in companies where most of the code is written using TypeScript.
What JavaScript Skills Do Employers Look For?
Employers usually want more than someone who knows basic JavaScript syntax. They want developers who can use JavaScript to solve real problems.
A good JavaScript developer should understand how variables and functions work and should be comfortable working with arrays and objects. They should also know how to handle user actions, work with web pages and communicate with a server.
Modern JavaScript also includes features that make it easier to work with tasks that take time, such as loading information from an online service. Developers should understand promises and async and await because these are common in modern applications.
Employers may also expect developers to understand how JavaScript works in the browser. Knowing how a page is changed through JavaScript, how events work and how information is sent to a server can be valuable during everyday development.
Most importantly, employers want developers who can take these skills and use them to build something useful.
What TypeScript Skills Do Employers Look For?
Once you understand JavaScript, TypeScript becomes easier to learn. Employers using TypeScript generally want developers who understand its main features and can use them naturally while building applications.
TypeScript allows developers to describe what kind of information a variable, function or object should contain. This can make code easier to understand and can help catch mistakes before the application is released.
Developers should become comfortable with basic TypeScript features such as types, interfaces, unions and type aliases. They should also understand how TypeScript works with functions, objects, arrays and classes.
However, employers are not usually looking for someone who has memorized every TypeScript feature. They want someone who knows when and why to use TypeScript.
A developer who understands the purpose behind the language will usually be more useful than someone who knows many advanced features but struggles to build a working application.
JavaScript vs TypeScript for Entry-Level Jobs
For people starting their careers, JavaScript is usually the better first skill to learn. It gives you the foundation needed to understand web development and makes it easier to learn TypeScript later.
Learning only TypeScript without understanding JavaScript can create problems. When you work on a real project, you will still encounter JavaScript concepts everywhere. You may also need to read older JavaScript code written before the company adopted TypeScript.
This does not mean beginners should avoid TypeScript. In fact, learning TypeScript after gaining a comfortable understanding of JavaScript can make a beginner more attractive to employers.
A strong beginner could understand JavaScript fundamentals, build a few small applications and then convert or rebuild one of them using TypeScript. This shows employers that the developer understands both languages and knows how they relate to each other.
Which One Is More Valuable in the Workplace?
The answer depends on the company and the job.
Some businesses still have large JavaScript codebases. Others use TypeScript for most of their newer development work. Some companies use both at the same time.
For this reason, saying that TypeScript has completely replaced JavaScript would be incorrect. JavaScript remains essential, while TypeScript has become an increasingly useful additional skill.
For many developers, the most valuable combination is JavaScript plus TypeScript. JavaScript gives you the basic knowledge, while TypeScript helps you work effectively on larger applications where keeping code clear and safe is important.
Employers also care about the developer’s ability to learn. Technology changes quickly, so companies do not always expect candidates to know every tool they use. A developer who understands the basics well can often learn a new tool much faster.
What About React and Other Popular Tools?
JavaScript and TypeScript are only part of what employers may expect from a web developer. Many jobs also involve a tool such as React, Angular or Vue.
React is particularly common in modern web development, and TypeScript is widely used with React projects. A developer who knows JavaScript, TypeScript and React can therefore apply for a broad range of frontend positions.
The same idea applies to server-side development. Developers working with Node.js may use JavaScript or TypeScript to build services and applications.
This is why it is useful to think about skills as a connected group rather than asking which single language will get you hired. JavaScript is the foundation, TypeScript adds another useful layer, and a popular development tool can help you apply those skills to real projects.
Do Employers Care About Projects?
Yes. For many junior developers, practical projects can be just as important as knowing the names of different languages.
A candidate who says they know JavaScript and TypeScript may not stand out very much if they cannot show how they have used those skills. A candidate who has built useful applications can give employers something concrete to evaluate.
For example, a developer could create a task management application using JavaScript and then create another version using TypeScript. This gives them an opportunity to understand the differences between the two and explain their choices during an interview.
Projects also help developers discover their own weaknesses. Something that seems easy while studying can become much more challenging when building a complete application.
The goal is not to create a huge project. A small application that works properly and is easy to explain can be more useful than a large project that the developer barely understands.
Should You Learn JavaScript or TypeScript First?
For most people, JavaScript should come first.
Start by learning how JavaScript works and spend enough time building small applications to become comfortable with it. Once the basic ideas feel natural, move to TypeScript.
This approach prevents TypeScript from feeling like a completely separate language. Instead, you will see it as an extension of skills you already have.
You also do not need to wait until you become an expert in JavaScript before touching TypeScript. Once you understand the main JavaScript concepts and can build simple applications, you can start learning TypeScript while continuing to improve your JavaScript skills.
Over time, the two can be learned together.
How the Job Market Is Changing
The needs of employers change as web applications become larger and development teams become more organized. TypeScript has benefited from this change because it can make large codebases easier to understand and maintain.
At the same time, JavaScript remains deeply connected to the web. Even developers who mainly use TypeScript need to understand JavaScript because TypeScript code eventually becomes JavaScript that browsers and other environments can run.
This means JavaScript is unlikely to become an unnecessary skill for web developers. Instead, TypeScript is becoming an important addition to the JavaScript skill set.
For someone preparing for the job market, this is actually good news. Learning JavaScript gives you a strong base, while adding TypeScript can help you meet the requirements of more modern development teams.
What Should You Put on Your Resume?
If you know both languages and can use them in real projects, it makes sense to mention both.
However, avoid simply filling your resume with technology names. Employers want to understand what you can actually do with those skills.
Instead of only saying that you know JavaScript and TypeScript, describe the applications you built and how you used the languages. Mention the problems you solved, the features you created and the tools you worked with.
This gives employers a better idea of your practical ability.
Your portfolio can support your resume as well. A few well-made projects can show that you understand the technology instead of simply having studied it.
Final Thoughts
So, JavaScript vs TypeScript is not really a question of choosing one and forgetting the other.
JavaScript is the foundation, while TypeScript is an increasingly valuable skill for working on modern and larger applications. Employers may look for either one depending on the company, but knowing both can give developers more opportunities.
If you are a beginner, start with JavaScript. Learn how websites and applications work, practice regularly and build real projects. Once you are comfortable with the basics, add TypeScript to your skills.
For experienced developers, learning TypeScript can also be a smart career move, especially if you want to work with companies building large web applications.
The strongest approach is simple: learn JavaScript well, understand TypeScript and focus on using both to solve real problems. That combination can make you better prepared for the skills employers need today.
