ES6 Vs TypeScript: What is the Difference?

In this article, we will see the comparison of es6 vs typescript with advantages and disadvantages.

What is TypeScript

TypeScript is an object-oriented programming language that is free and open-source. It’s a superset of JavaScript that’s highly typed and compiles to ordinary JavaScript. Microsoft created and maintains TypeScript under the Apache 2 license. It is not a browser-based application. To compile and produce a JavaScript file, you’ll need a compiler. The “.ts” suffix refers to the TypeScript source file. By renaming any valid “.js” file to “.ts” we may utilize it. TypeScript is an ES6-based version of JavaScript with a few more capabilities.

Histroy of TypeScript

The typeScript was created by Anders Hejlsberg. It was originally made available to the general public on October 1, 2012. The latest version of TypeScript 0.9 was published in 2013  after two years of internal development at Microsoft. TypeScript 4.5.4, which was published on 13 December 2021, is the most recent version.


ECMAScript (ES) is a standardized scripting language developed by ECMA International. It was intended to bring JavaScript up to the same level as other programming languages. There are various implementations of the ES programming language, the most prominent of which is JavaScript. ECMAScript is mostly use by web developers for client-side scripting (WWW).

ECMAScript6 or ES6 is the sixth version of the ECMAScript standard, which was eventually rename as ECMAScript 2015. It’s a significant improvement to the JavaScript programming language, which allows us to create complicated apps. It has a number of features aimed at making large-scale software development easier. Chrome and Firefox are the most popular ES6 web browsers. A transpiler transforms ES6-based code into ES5, which is support by a wide range of browsers. A transpiler is a program that converts one language into another. Other transpilers to build the modules include Grunt, Gulp, and Babel. As a result, TypeScript is compatible with ES6.

Histroy of ES6

Brendan Eich introduced JavaScript in May 1995. It was originally known as Mocha, after Netscape creator Marc Andreessen, and was eventually renamed to LiveScript. Sun Microsystems held the JavaScript trademark at the time. Netscape purchased a trademark license in December 1995 and renamed it JavaScript.

Netscape took JavaScript to the ECMA standards group in 1996 and 1997 to maintain a definition for the language. The ECMA Technical Committee 39 (TC39) was established in June 1997 to continue the evolution of the language, finally producing ECMA-262 Ed.1.

ECMAScript 1, the first standard version of JavaScript, was released in June 1997. And ECMAScript 2 was issued a year later, with just minimal changes to maintain a parallel ISO standard for JavaScript. ECMAScript 3 was launched in December 1999, and it includes many of the popular features of JavaScript. ECMAScript, formerly known as ES6, was released in December 2009 and was later renamed ECMAScript 2015.

ES6 Vs TypeScript

DefinitionTypeScript is a free and open-source pure object-oriented programming language. It is developed and maintained by Microsoft.ES6 is a version of ECMAScript (ES), which is a scripting language specification standardized by ECMA international.
ExplanationTypescript is to eradicate the development errors.ES6 is comparatively more flexible in development time.
Data-TypesTypeScript supports all primitive data types.ES6 does not support all data types.
FeaturesTypeScript contains features such as generics and type annotations, Inference, Enums, and Interfaces.ES6 does not support these features.
ScopeTypescript has three scopes.
1) Global Scope
2) Class Scope
3) Local Scope
ES6 has two scopes
1) Global Scope
2) Local Scope
Decision-Making1) if Statement
2) if-else Statement
3) else…if and nested if statements
4) switch Statement
1) if Statement
2) if-else Statement
3) The else- if ladder/nested if statements.
4) switch?case Statement
ModulesTypeScript Modules are of two types:
1) Internal
2) External modules
ES6 modules classify in two ways:
1) Importing a module
2) Exporting a module
LoopTypescript and ES6 both are having the same loops. Definite and IndefiniteTypescript and ES6 both are having the same loops. Definite and Indefinite

If you are thinking as a developer then the following differences come into mind

For TypeScript:

  • Typesafe
  • JavaScript superset
  • Powerful type system, including generics & JS features.
  • Aligned with ES development for compatibility.
  • Structural, rather than nominal, subtyping.
  • Compile-time errors.
  • Starts and ends with JavaScript.

For ES6:

  • ES6 code is shorter than traditional JS
  • Module System Standardized
  • Extremely compact
  • Destructuring Assignment

Conclusion of ES6 Vs TypeScript

When comparing Typescript with ES6, Typescript, in my perspective, has more advantages. Another significant benefit of typescript is that it does a fast sanity check on all JS files to detect syntax issues. It’s simple to switch from JavaScript to Typescript.
