Ultimately the choice of any tech-stack will depend upon how complex it is to write codes in it. The more complex language requires hiring an app developer with high-end experience which will add up to a huge cost to your development project. 

And if it comes to choosing between TypeScript Vs JavaScript- both have different approaches. 

TypeScript adds complexity through static typing, requiring developers to define types for variables, parameters, and return values. While this can enhance code reliability, it introduces additional syntax and concepts.

Example:

TypeScript

function greet(name: string): string {

    return `Hello, ${name}!`;

}

In this example, “: string” specifies that the “name” parameter and the return value are expected to be strings.

Coming to the other side, JavaScript offers simplicity with its dynamic typing, where types are inferred at runtime. This makes JavaScript code more concise and easier to write and no high-level of coding skills are required. 

Example:

javaScript

function greet(name) {

    return `Hello, ${name}!`;

}

Here, “name” can be of any type without explicit declaration, allowing for flexibility but potentially increasing the risk of runtime errors.

How does TypeScript Differ from JavaScript?

Let us understand the differences when it comes to TypeScript vs JavaScript. 

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. It offers classes, modules, and interfaces to help you build robust components. TypeScript is often used for large-scale applications and transpires down to older versions of JavaScript.

JavaScript is a lightweight, interpreted programming language with object-oriented capabilities that allows developers to create dynamic web pages. With Node.js, JavaScript can be used to create servers using the event-driven, non-blocking I/O model (Node.js). 

Web developers typically use JavaScript in two ways: client-side development using top frontend frameworks like AngularJS or ReactJS, or on the server side using Node.js with frameworks like ExpressJS or Koa.
