Difference between Web development on JavaScript vs Typescript

Confused about which one should learn JS or TS? If you’ve worked on a web development project, you likely know how JavaScript functions. JavaScript has been around for many years and is one of the most popular scripting languages in the developer community. However, whenever a technology or language becomes popular, there’s always a new alternative that offers competition. One such competitor is TypeScript. As TypeScript gains popularity, it's seen as an improved version of JavaScript with additional features. TypeScript is an open-source programming language created by Microsoft in 2012. It was designed to handle large, complex applications. Today, many web development projects, including Angular, use TypeScript for their services. 

A study found that TypeScript and JavaScript rank as the second and third most preferred programming languages among developers. But why is JavaScript so popular? JavaScript is widely used as the primary scripting language for developing apps and web pages. It’s versatile and works for both frontend and backend development. Frameworks like TezJS and React use JavaScript on the front end, while Node.js and Deno support backend development. Web development on JavaScript continues to be highly relevant due to its flexibility and vast use in creating modern web applications. While TypeScript is a great alternative for larger applications, JavaScript remains the foundation for many successful web development projects.
 

Difference b/w Web development on Javascript and Typescript:

When comparing TypeScript vs JavaScript, it’s important to know that all JavaScript code is valid in TypeScript. This means TypeScript is a superset of JavaScript. In simple terms, if you rename your JavaScript file (.js) to a TypeScript file (.ts), it will still run just fine. But, even though the two languages are related, they are not exactly the same. Let’s take a closer look at both. JavaScript was originally created as a client-side programming language, meaning it was mainly used to make web pages interactive. Over time, developers realised that JavaScript could also be used on the server side, leading to its use in both frontend and backend web development on JavaScript. However, as JavaScript grew more popular and was used for larger projects, it started becoming difficult to manage. The code could become complex and harder to understand, and it didn’t fully support the features of an object-oriented programming language. Because of these limitations, JavaScript wasn’t considered the best option for large-scale, server-side projects.  

This is where TypeScript comes in. TypeScript was developed by Microsoft to fill the gaps in JavaScript. It is an open-source, object-oriented programming language, and is seen as an improved version of JavaScript. TypeScript offers features like static typing, which allows you to catch errors early in your code. It also provides classes, namespaces, and other features that make managing large codebases easier.

Though TypeScript adds new features, it still compiles down to regular JavaScript. This means that all JavaScript libraries work perfectly fine with TypeScript. Essentially, web development on JavaScript can also benefit from TypeScript's features, giving developers more tools to work with. TypeScript helps make JavaScript more powerful by adding useful features for large applications. While JavaScript is still the foundation for web development, TypeScript is quickly becoming a popular choice for developers working on more complex projects.

Final Words: 

In conclusion, both JavaScript and TypeScript are powerful tools for web development. JavaScript is flexible and widely used for both frontend and backend projects, making it the foundation of many web applications. However, TypeScript, with its added features like static typing and better code management, is becoming a popular choice for handling large and complex projects. While web development on JavaScript remains essential, TypeScript helps developers catch errors early and work more efficiently, making it a great option for larger-scale web development projects.
