ECMAScript 3 vs ECMAScript 6
Developers should learn ES3 to understand the historical evolution of JavaScript and to maintain or debug legacy codebases that were built before modern ES5+ standards meets developers should learn es6 because it provides essential modern javascript features that improve productivity and code quality, such as arrow functions for concise syntax and classes for object-oriented programming. Here's our take.
ECMAScript 3
Developers should learn ES3 to understand the historical evolution of JavaScript and to maintain or debug legacy codebases that were built before modern ES5+ standards
ECMAScript 3
Nice PickDevelopers should learn ES3 to understand the historical evolution of JavaScript and to maintain or debug legacy codebases that were built before modern ES5+ standards
Pros
- +It is particularly useful for working with older web applications, libraries, or systems that rely on ES3 compatibility, such as some enterprise software or embedded environments
- +Related to: javascript, ecmascript-5
Cons
- -Specific tradeoffs depend on your use case
ECMAScript 6
Developers should learn ES6 because it provides essential modern JavaScript features that improve productivity and code quality, such as arrow functions for concise syntax and classes for object-oriented programming
Pros
- +It is widely used in web development for building interactive front-end applications with frameworks like React or Angular, and in Node
- +Related to: javascript, typescript
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use ECMAScript 3 if: You want it is particularly useful for working with older web applications, libraries, or systems that rely on es3 compatibility, such as some enterprise software or embedded environments and can live with specific tradeoffs depend on your use case.
Use ECMAScript 6 if: You prioritize it is widely used in web development for building interactive front-end applications with frameworks like react or angular, and in node over what ECMAScript 3 offers.
