TypeScript Vs JavaScript

JavaScript is a client-side programming language but the addition of node.js makes it a server-side technology. It is used to create interactive web pages. But, it doesn’t include object orientation, strong type checking, compile-time error checks, etc. Moreover, the lengthy code becomes difficult to handle. TypeScript resolves all these issues to make JavaScript a full-fledged server-side technology at the enterprise level. So, simply TypeScript is JavaScript for application-scale development. Let us delve deeper to know the advantages, disadvantages, and differences between TypeScript and JavaScript languages.

Advantages of TypeScript

Being the super-set of JavaScript, TypeScript has numerous benefits as follows:

• It helps the developer to write robust and clear code as the feature of static typing points the errors while writing scripts.
• Type annotations identify the constructs that can possibly be errors.
• It provides better collaborations for large projects where a number of developers work simultaneously.
• With TypeScript, one can use better documentation tools e.g Fetch API as compared to JavaScript.
• It has many in-built features like auto-compilation, ECMAScript 6 code support, and dynamic typing that gives enhanced productivity.

Disadvantages of TypeScript

• It does not support abstract classes.
• It takes more time due to the compilation phase.

Advantages of JavaScript

• Some developers still prefer JavaScript over TypeScript because of the flexibility it offers.
• It is a better choice for small projects.
• If one already has a JavaScript developer team that can implement test-driven development, there is no need to bear the cost of TypeScript.
• JavaScript is directly converted into machine language so saves time by skipping the compilation phase.
• JavaScript requires no annotations that make it more efficient than TypeScript.
• It has an easy learning curve as compared to TypeScript.

Disadvantages of JavaScript

• JavaScript code is viewable to the user, others may use it for malicious purposes.
• A single code error can stop the rendering of the entire JavaScript code on the website.
• Different browsers can interpret it differently, making JavaScript a little unreliable.
• Although some HTML editors support debugging, it is not as efficient as other C/C++ editors.

In a word

JavaScript is widely used but the TypeScript is gaining popularity day by day. Being the superset of JavaScript, TypeScript has more benefits. Many of the tech giants have already adopted it.
