What is TypeScript?

Microsoft created and maintains the TypeScript programming language. It's a syntactical superset of JavaScript with the addition of static typing as an option. TypeScript is a programming language for large-scale applications that compiles to JavaScript. Both client-side and server-side JavaScript applications may be built with TypeScript. Trans compilation can be done in a variety of ways.

What is its use?

JavaScript (also known as ECMAScript) began life as a simple browser scripting language. It was supposed to be used for tiny bits of code embedded in a web page when it was conceived; writing more than a few dozen lines of code would have been exceptional. As a result, early web browsers took a long time to run such code. However, JS grew in popularity over time, and web developers began to use it to create interactive experiences. As a result of the rising use of JS, web browser makers optimized their execution engines and expanded what could be done with it, encouraging web developers to use it even more. Your browser is regularly running programs that span hundreds of thousands of lines of code on current websites. This is the evolution of "the web" from a simple network of static pages to a platform for rich applications of all kinds over a long period of time.

Reasons why you should choose TypeScript over JavaScript

TypeScript is more reliable

In comparison to JavaScript, TypeScript code is more trustworthy and easier to refactor. This makes it much easier for engineers to prevent mistakes and change code. When developing new code or refactoring, types invalidate most of the trivial errors that can slip into JavaScript codebases and establish a speedy feedback loop to address all of the small issues.

TypeScript is more explicit

Making types clear draws our attention to the details of our system's construction and the interactions between its many components. It's critical in large-scale systems to be able to abstract away the rest of the system while maintaining context. We can do this because of types.

Precise defining through typing

When examining TypeScript's advantages, we must first consider its most essential feature: the type system.

Developers who code in languages with extensive and rigorous type systems, such as C# or Java, prefer to mock dynamically typed languages, arguing that faults in apps created in those languages are discovered by the end-user rather than the compiler. But, jokes aside, there is a real problem with JavaScript.

In TypeScript, on the other hand, if your developer makes a mistake and inserts unsupported input into the code, they'll be notified before the work is pushed to the repository. Even if they choose to disregard the issue, CI/CD systems such as Jenkins can verify types and prohibit them from being pushed further into production.

It's a lot easier to maintain your code with types when you can identify these obvious but commonly recurring issues early.

Types make code management easier

Types can help developers in a variety of ways, including early detection of issues in builds. WebStorm and other modern programming environments can provide more precise code suggestions.

Even at this level, you can be informed if your code has type errors. There's no need for you to do a build because the faults aren't identified by the user or the compiler, but by the editor itself.

Providing types is also a form of code documentation. Even simple documentation can be advantageous to your engineers, at the very least since they won't have to waste their time generating it themselves. This is known as "self-documenting code," because one developer develops something and others can figure out what it does and how it works just by looking at it.

Increased team performance

The beauty of precisely typed programming languages is that they allow your developers to focus on their tasks without having to rely on the rest of the team. One of the greatest benefits of cooperation is having someone to question about anything that pertains to your project, but doing so too frequently is a warning indicator. Context switching and asking questions rather than writing code has an impact on performance and results in tasks not being completed by the end of the sprint.

TypeScript makes it easier to bring on additional developers to your project. Explicitly specified data structures and type annotations make it far easier to understand the decisions made by the engineers who created your code in the first place.

Fast refactoring

To keep the codebase resilient and manageable, refactoring or updating the app without changing its behavior is required. This crucial step is made easier with TypeScript. Because IDEs know so much about your code, navigation functions like "find all references" and "navigate to definition" are available.

Furthermore, many errors are detected automatically. For example, TS will notify you if you rename a function and then forget to change the name somewhere else. This makes reworking easier and faster, which is especially useful when dealing with huge chunks of code.

How much do typescript developers make?

In the United States, the average typescript developer pay is $125,000 per year or $64.10 per hour. Starting salaries for entry-level employment start at $110,000 per year, with the highest-paid professionals earning up to $150,150 per year. In the United States, the highest annual income for a Typescript Developer is $137,579 dollars.
