TypeScript Vs JavaScript Vs ECMAScript – Know the difference

What is JavaScript? 

JavaScript is a scripting language for building dynamic sites. It is adhered to client-side development principles, meaning it runs entirely within the user's web browser and requires no resources from the webserver. JavaScript also can be used with alternative technologies like REST API (Application Programming Interface), XML, and others. 

The goal of creating this script is to make it a scripting language that complements Visual Basic and C++ in Microsoft's language families. JavaScript, on the other hand, is not intended for huge, complicated applications. It was created for applications with less than a thousand lines of code. 

What is TypeScript? 

TypeScript is a JavaScript programming language for today. It is a statically built language for writing JavaScript code that is simple and straightforward. It can be used with Node.js or any browser that supports ECMAScript 3 or above. 

Static typing, classes, and an interface are all available in TypeScript. Adopting Typescript for a large JavaScript project can result in more robust software that is easily deployable with a typical JavaScript application. 

What is ECMAScript? 

ECMAScript (ES) is a standardised scripting language developed by ECMA International. It was intended to bring JavaScript up to par with other programming languages. There are various implementations of the ES programming language, the most popular of which is JavaScript. ECMAScript is mostly used by web developers for client-side scripting (WWW). 

ECMAScript6 or ES6 is the sixth edition of the ECMAScript standard, which was eventually renamed ECMAScript 2015. It is a significant improvement to the JavaScript programming language, which allows us to create complicated apps.

It includes several features aimed at making large-scale software development easier. Chrome and Firefox are the most popular ES6 web browsers. A transpiler is used to transform ES6-based code into ES5, which is supported by a wide range of browsers.

A transpiler is a programme that converts one language into another.

The Main Difference Between Typescript and JavaScript 

  1. Typescript is a superset of JavaScript, which is a scripting language that enables you construct interactive web pages. 
  2. JavaScript code does not need to be compiled, whereas Typescript code must. 
  3. When comparing TypeScript with JavaScript, TypeScript has a prototyping feature that JavaScript does not. 
  4. Typescript use ideas such as types and interfaces to describe the data being utilised, whereas JavaScript does not. 
  5. For large projects, Typescript provides a robust type of system with generics and JS capabilities, whereas JavaScript is an excellent choice for small projects.

Features of JavaScript

  1. It is a platform-independent language. 
  2. It is utilised on both the client and server sides. 
  3. It is simple to pick up and use. 
  4. It is a dynamic language that is both versatile and powerful. 
  5. Using JavaScript, you have 'the enormous freedom' to do whatever you wish. 
  6. Workflow for Effective Testing. 
  7. Added Requirements.

Features of Typescript

  1. Viability 
  2. Offers incredible usefulness for engineers. 
  3. Code route and bug avoidance. 
  4. Code 'discoverability' and refactoring. 
  5. Discretionary Static Type Annotation/Static Typing. 
  6. Extra Features for Functions. 
  7. Upholds ES6. 
  8. Upholds interfaces, sub-connection points, classes, and subclasses. 
  9. Adaptable HTML5 client-side turn of events. 
  10. Rich IDE accessible with autocomplete and code route highlights. 
  11. Class-based object-arranged with the legacy of private individuals and points of interaction.

Why JavaScript? 

  1. Open-source project with Microsoft's support. 
  2. Exceptionally planned device for little scripts. 
  3. Upholds classes, interfaces, and modules. 
  4. Incorporated JavaScript runs in any program. 
  5. Permits cross-assemblage. 
  6. You can broaden JavaScript for composing enormous applications. 
  7. Adds support for classes, points of interaction, and modules. 

Why TypeScript? 

  1. TypeScript upholds JS libraries and API Documentation. 
  2. It is a superset of JavaScript. 
  3. It is alternatively composed prearranging language. 
  4. TypeScript Code can be changed over into plain JavaScript Code. 
  5. Better code organizing and object-arranged programming procedures. 
  6. Permits better advancement time instrument support. 
  7. It can expand the language past the standard decorators, async/anticipate.

Why ECMAScript?

  1. JavaScript ES6 brings new syntax and new awesome features. 
  2.  Make your code more modern and more readable.  
  3. It allows you to write less code and do more. 
  4. ES6 introduces us to many excellent features like arrow functions, template strings, class destructors, modules, and more.

TypeScriptES6
All primitive data types are supported by TypeScript.ES6 does not support all data types.
Generics and type annotations, as well as Inference, Enums, and Interfaces, are all included in TypeScript.ES6 does not support these features.
Typescript has three scopes:     Global Scope Class Scope Local ScopeES6 has two scopes:     Global Scope Local Scope
TypeScript Modules are of two types:     Internal External modulesTypescript and ES6 both are having same loops:     Definite Indefinite
Typescript vs ECMAScript

Summary 

JavaScript is a scripting language that allows you construct dynamic web pages, whereas TypeScript is a modern-day JavaScript development language. TypeScript employs ideas like types and interfaces to explain the data that is being utilised, but JavaScript does not have such a concept. Typescript is the best option if you have a development team with experience and knowledge.
