Major benefits of the new ES6 update
If we delve into the features of this new ES6 update, the new edition comes with a wide range of features, in the following paragraphs will discuss each paragraph in detail.
Modules are one of the new inclusions in the newly rolled out update by ECMA. The Modules allow the user to reuse some portions in their applications in other areas. The feature also allows the user to import and export keywords and also load the dependencies and manage them.
This feature helps you in handling errors arising from asynchronous operations. Though you can handle such errors using a callback method, but promises are much easier as they are in the readable format.
Arrows uses a syntax =>. Though this not such a notable addition in ES^, but still it is useful for the users as it is a substitute for the keyword “this”.
The “Const” feature ensures that the code is accurate. This feature also helps in reducing the bugs and if anyone tries to change the code that should not be modified then this feature throws of an error.
- Template Literals
Template literals feature allows the user to change variables into strings. Template strings are lets you use a tag for auto-escaping SQL strings.
- Sugar Syntax
The new ES6 has simplified the syntax, making it more readable and easily understandable. ES6 comes with a new syntax class called “syntactic sugar” which supports syntax simplification. Though this new class does not change the way system works but it provides a cleaner syntax.
- Block Level Scoping
In ES6, the users can use “Let” keyword scope variables directly for blocks.
- Rest Parameters
One major feature of the new ES6 update is that the user does not have to make use of arguments to access arguments for functions, they can do that by accessing arrays that represent the remaining parameters.
- Default Parameters
If you've ever wanted a function parameter that could set a default value, you are in luck, because ES6 has this functionality.
The “Set” feature allows You can store a data values list inside a collection object.
Though this feature was present in the ES5, but it did not allow the user to use a variable right in an object literal. In ES6, the user can use this feature with a specific syntax.
Constraints of ES6 Update
Though this new update has ringed in many advanced features, but still has few backlogs:
- Difficult to make changes:
- Does not support 64-bit numeric type:
- The newly rolled update ES6 does not support 64-bit numeric type. It only offers support to the doubles due to its support for floating-point operations.
