Understanding JavaScript and TypeScript in detail

Along with HTML and CSS, JavaScript is one of the essential building elements of the internet. Most web developers at app development companies in Virginia begin by studying those three languages, irrespective of whether they want expertise in frontend or backend development.

However, Typescript, a programming language based on JavaScript, has swiftly grown in popularity in recent years, establishing itself as another key online technology. The contrasts between the two languages and their connection are examined in this article to determine if TypeScript may be called a JavaScript replacement.

What is JavaScript, and how does it work?

JavaScript is a scripting language that was designed to work with dynamic HTML in internet browsers. It was used to embed “logic” into web pages so that user interactions could be analyzed, content could be updated, and new material could be produced. JavaScript, like HTML and CSS, is a standard web development tool. However, it may also be found on servers and in microcontrollers.

JavaScript was first released by Netscape in 1995 as LiveScript and was renamed JavaScript after a collaboration with Sun Microsystems (then the developer of Java). Despite the fact that Java and JavaScript have distinct underlying principles and were created separately, the name change was meant to increase the popularity of JavaScript by using the existing well-known ‘Java’ brand.

Javascript is a programming language with an ECMAScript language core that may be employed for object-oriented, primitive, or functional programming depending on the situation. The ECMAScript language core outlines a scripting language that is dynamic, typed, object-oriented, and classless.

What is TypeScript, exactly?

Microsoft created TypeScript, a programming language based on the ECMAScript standard for JavaScript. JavaScript is regarded as a superset of TypeScript. This implies that any JavaScript code is acceptable TypeScript code, and thus software companies in VA may use popular JavaScript frameworks like AngularJS and Ionic with TypeScript. The tightly typed programming language can handle arbitrary data types and employs ideas like object alignment and type inference to express data.

 In the domain of large-scale application development, Microsoft aimed to address the drawbacks of the JavaScript programming language. Microsoft developed TypeScript, a JavaScript-based alternative to JS, to provide a better enterprise-scale solution.

The developers, led by Anders Hejlsberg, set out to create TypeScript in such a way that JavaScript’s compatibility and platform independence would not be jeopardized. As a result, TypeScript now has an expanded JavaScript compiler that can convert code into JavaScript, allowing TypeScript to execute in the browser.

What are the similarities and differences between TypeScript and JavaScript?

TypeScript is a descendant of JavaScript built on ECMAScript, JavaScript’s standardized language core. Another unique characteristic of TypeScript is that it is a superset of JavaScript, allowing it to leverage JavaScript libraries like Angular.

The program code, formerly solely enabled by Visual Studio Code, is now backed by various IDEs and is frequently used by developers in conjunction with JavaScript. TypeScript is closely related to JavaScript and may be thought of as a “super-category.” It’s no surprise, then, that TypeScript, like JavaScript, is widely utilized in web development.

JavaScript is impossible to avoid in modern web development, which is one of the key reasons it was the most widely used scripting language in 2021.

On the other hand, the graph below shows how popular TypeScript is among programmers and project sponsors. According to StackOverflow’s annual Developers Survey, TypeScript is the second most desired computer program behind Python as a new talent to acquire.

The rising popularity of TypeScript within the software engineering community is predicted to result in a significant upward trend in its use in the future and the continuing growth of the language’s growing community of software resources.
