The ES6 or ECMAScript 2015 came with various exiting and new features. These features make it a more robust and updated programming language than ES5. Some of these new promising features are Const and let statement, Template string, arrow functions, and many others.
The ECMAScript 2015 programming language, added with functional, dynamic, structural, and prototype-based features such as-
- Structural and Vital
- Effective and Dynamic
The ECMAScript 2015 was typed dynamically. The ES6 provides a facility named Duck Typing, to perform testing of the objects. The typed script in ECMAScript 6 is added with a value instead of an expression.
- A Weakly-Typed Language
A weakly typed language can be determined as a language in which the variable does not wrap with a particular data type group. ECMAScript 6 is a weakly typed programming language. It means we can initialize a type according to the operation. The ECMAScript 6 have several characteristics to change the variable from one type to another type.
- Supports Transpiling Feature
The Transpiling process includes an extra step when the user writes the code; sometimes, it is necessary to prevent the Polyfills.
Apart from the features mentioned above, ECMAScript 6 includes some following new features-
- Default Parameter Values
- Exponentiation (**)
- Array. find ()
- Array. find Index ()
Browsers for ECMAScript 6
The Google Chrome version 58 (January 2017) fully supports the ECMAScript 6. The Chrome version 4 to Chrome 41 does not support the ES6 code.
The old Mozilla Firefox versions do not support the ES6. Mozilla Firefox Browser version 54 (May 2017) fully supports the ECMAScript 2015. The old versions from version 2 to Firefox version 44 do not support the ES6.
Browser version 14 released in August 2016 fully supports the ECMAScript 2015 programming language, but the old version of the edge does not support the ES6.
Apple developed this web browser. The new version of browser Safari 10 (released in July 2016) fully supports ES6. The old versions of Safari do not support ES6.
Opera is a web browser developed by Opera Software for Microsoft Windows, Android, Mac Operating System, and Linux Operating System. The new version of Opera 55 (launched in August 2018) fully supports ECMAScript 2015. The old versions do not support ECMAScript 6.
Text/Source-Code Editors and IDE for ECMAScript 6
The text editor can be defined as a program or software in a computer that is used to edit or create a programming language file. Different editors are used for implementing different programming languages. Various editors are used for different operating systems. For Example, Microsoft Windows comes with Microsoft Notepad (Generally called “Notepad”), Unix, and similar to Unix programming operating system come with Pico editor or its other variants.
On the other hand, the Source-code editors can also be determined as a text editor. It is a program that is specially designed to perform editing in the source code of computer software. For example, NetBeans, Eclipse, Brackets, and Visual Studio (VS), etc.
There are following editors given below that supports ECMAScript 2015-
Why We Use ECMAScript 2015?
There are some reasons given below that describes why we need to use ECMAScript 6.
- ECMAScript 6 is a fast and efficient language
- ECMAScript 6 have Backward Compatibility
- ECMAScript uses Object-oriented Classes
ES6 uses Class syntax. In ECMAScript 6, we have to define Classes, maps, and inheritance traditionally. ES6 maps these Classes and inheritance according to the prototype chain. This change can make ECMAScript 6 very easier for Object-oriented programming.
- ECMAScript 6 supports Arrow Function
It is because the function “this” sets the value until the developer wrap the variable. Sometimes it is a difficulty for the user.
- ES6 supports const and let keywords
Declaration of let
Declaration of Const
- ECMAScript 2015 support Promises
- ECMAScript 6 has a Spread operator concept
The Spread operator provides a way for the developer to create new arrays according to the values of pre-declared arrays. The Spread operator is a single versatile construct in ECMAScript 2015 programming language. It is a little bit similar to the Splat operator used in Ruby programming language.
The Spread operator helps developers to work with more than one array at a time. It can perform the following tasks-
- It can copy a whole array with value.
- It allows us to insert a new value in the array.
- It also performs the concatenation of arrays.
- ECMAScript 6 supports Template Literal Strings
- The Modules are created in ECMAScript 2015
- ECMAScript 6 (ES6) use the term YARN
Advantages of ECMAScript 6
There are some essential advantages of ECMAScript 6 mentioned below-
Drawbacks of ECMAScript 2015
ECMAScript also has some drawbacks or disadvantages of ES6 given below-
- In ECMAScript 2015, the debugging cycle becomes a program code that may have bugs. It is not a concern with reloading and editing.
- In the code development, the developer’s code will not exactly match with our code, so the indication being less helpful.
- The separate modifications are may be small, but they will make a significant change.
