JavaScript and TypeScript are two of the most widely used programming languages today. While all of these programming languages are primarily used for web application creation, TypeScript has recently gained popularity as a result of RxJS and Angular’s adoption.
So, do you switch from JavaScript to TypeScript for your web app? This blog will undoubtedly have an answer to that issue. JavaScript is a scripting language that allows you to build interactive web pages in its most basic form.It is a client-side programming language that does not rely on web server resources.
The main goal in creating this language was to create a scripting language that would complement Microsoft’s Visual Basic and C++. You can now use JavaScript with a variety of technologies, including XML, REST APIs, and more. JavaScript, on the other hand, was never intended to be used to create complex applications.
History of JavaScript
Brendan Eich, a NetScape Communications Corporation programmer, developed JavaScript, which was originally intended to act as a Netscape navigator.
But it quickly gained popularity as a scripting language, and it was renamed JavaScript to reflect NetScape’s support for Java in its web browser.
We’ve mentioned a few significant JavaScript milestones since its inception below.
- JavaScript was first released in September 1995 under the name Mocha. The first scripting language was created in just ten days.
- In November 1996, NetScape submitted JavaScript to ECMA (European Computer Manufacturers Association) after it became successful.
- ECMAScript 2 and ECMAScript 3 were released in 1998 and 1999, respectively.
- Mozilla and Eich collaborated to create E4X JavaScript in 2005.
- The CommonJS project was founded in 2009 with the goal of bringing the language closer to ECMAScript 6.
- In 2016, 92 percent of all websites on the Internet, including Facebook and Google, used JavaScript.
What is TypeScript?
Simply put, TypeScript is a modern-day, statically compiled JavaScript language for writing cleaner, easier-to-understand code.
Any browser that supports ECMAScript 3 or newer versions, like NodeJS, will run TypeScript. In other words, incorporating TypeScript into a JavaScript development project will aid in the development of more stable applications due to its static typing, classes, and user interface.
In a nutshell, TypeScript is a programming language for creating large-scale applications that can be converted to JavaScript. Microsoft developed TypeScript as an open-source programming language with static typing support.
TypeScript is essentially a superset of JavaScript, and it can be used to create both server-side and client-side JavaScript applications. We’ve mentioned a few significant JavaScript milestones since its inception below. Version 0.8 of TypeScript was released to the public in October 2012.In 2013, version 0.9 was released.
At Microsoft’s create developer conference in 2014, Microsoft introduced support for generics and launched TypeScript 1.0. Microsoft’s TypeScript development team launched a new TypeScript compiler in July 2014, reporting 5 times faster performance.
Microsoft launched TypeScript 2.0 in September 2016, which included many new features, including the ability to prevent variables from being assigned null values. Conditional forms were introduced to TypeScript in March 2018.
Benefits of JavaScript
JavaScript became popular due to below-mentioned benefits.
Adaptability
JavaScript has a lot of flexibility, which is why some developers prefer it to TypeScript. JavaScript code is compiled directly into machine language in native browsers, while TypeScript produces JavaScript after compilation, which adds an extra stage.
There are no annotations available
Since TypeScript allows developers to constantly annotate their code, it makes the project less effective. JavaScript, on the other hand, does not.
The learning curve is easy
Since JavaScript is so much easier to learn, many JavaScript developers still choose to use the JavaScript they already know over learning TypeScript.
A sizable population
The JavaScript community is massive, active, and growing. That means it’s easier to find developers who are willing to assist with project development and share their knowledge.
Benefits of TypeScript
Like mentioned in the beginning, TypeScript is gaining traction rapidly. And the main reason behind that is its benefits from additional features. Following are the best benefits of TypeScript.
Typing that is static
The static typing function in TypeScript aids in the detection of bugs when writing scripts. This aids developers in writing and maintaining more stable code, resulting in much stronger and cleaner code than JavaScript.
Type annotations
One of TypeScript’s key goals is to statically classify structures that may be errors.Annotations of some kind are welcome.One of TypeScript’s key goals is to statically classify structures that may be errors.This enables developers to make secure assumptions about state while the application is running.
More conducive to collaboration
Large-scale applications typically have a larger team of developers working on them. This gives you the chance to make a mistake and raise your coding errors. However, TypeScript’s type safety function aids in the detection of code errors and bugs during the writing phase rather than during compilation, resulting in a more effective debugging process and improved collaboration opportunities.
Documentation for APIs
With tools like Dash, you can access the library’s own documentation in JavaScript. However, it simply cannot compete with TypeScript’s experience.Consider the Fetch API. The image below demonstrates how developers can use the VSCode Peek function to explore the API.
