ES6 New Features

ES6 New Features

Introduction to ES6 New Features

The es6 new features are the concept for implementing the new ideas in the script for application implementation that will include all the new enhancements like modules, class declarations, lexical block changes, loop iterators, and generators that promise used for asynchronous programming technique destructuring patterns like an array, object, default parameters, const, let, template literals, tagged templates, expressions which validated the arrow functions spread and rest syntaxes.

Es6 New Features Overviews

The Modules, class declarations, lexical block scoping, iterators and generators, promises for asynchronous programming, destructuring patterns, and appropriate tail calls are among the significant changes. Additionally, the data abstractions, which include maps, sets, and arrays of binary numeric values, have been added to the ECMAScript libraries of built-in keywords, classes, methods, and support for Unicode extra characters in the strings and regular expressions. Finally, Subclassing allows for extending the built-ins in various ways.

Mainly it has been classified into three different categories to utilize the new features in the ecma6 scripts. The better way to utilise the syntax of the new features that already exist in the libraries includes classes, modules, and other new functionality in the standard library for the strings, arrays, maps, sets, and other collection classes, interfaces, and methods.

  1. Classes
  2. Modules
  3. Functionalities which includes Strings, Arrays
  4. Promises
  5. Collections like Maps, Sets
  6. Generators
  7. Proxies
  8. WeakMaps

All es6 new features

It has many types which we have discussed on the above, please find the below features.

ES6 Classes:

Among that ES6 classes aren’t a brand-new concept: They primarily give a more user-friendly syntax for creating an traditional function like Object() { [native code] } functions. Between the members of a class definition, there is no punctuation. Members of an object literal are separated by commas, which are forbidden at the top level of class declarations. Semicolons are permissible, but they are not used in the es6. The anticipation for the syntax that may include support for semicolons is terminated with the members, and semicolons are allowed in the es6 classes. There are two types of class definitions or techniques to declare a class, similar to functions: class declarations and class expressions.

ES6 Modules:

Despite the fact that JavaScript never has built-in modules, it has settled on a simple module style that ES5 and older frameworks support. But in ES6, it has embraced this look as well for Each module is just a chunk of codes that uses once in loaded rather than it will be executed. Along with there may be declarations of the codes, which include (variable declarations, function declarations, etc.). These declarations are kept local to the module by using default. It can be marked as exports, allowing other modules to import them with the same datas. Things it might be imported from other modules by a module. Also, it refers to those modules using module specifiers related to the strings types related to the below areas.

Strings and Arrays

Strings:

A string in JavaScript is an object that represents a string of characters. Most Strings are commonly used for to store text-based information like a name, description, cities, etc… Anyway, we used text enclosed in single or double quotes is treated as a string in JavaScript. In JavaScript, there are two ways to make a string: When you use a string literal, you can save a lot of time. Using the string object with the help of a new keyword.

Arrays:

An array is an object that represents a group of related objects. It enables for to store of many values or a collection of values in a single variable name. The Arrays are used to store collections of values that are ordered chronologically. A collection of homogenous elements, or a collection of values of the same data type, is what an array is. Any legal values, such as objects, numbers, characters, functions, and other arrays, can be stored, allowing us to design complicated data structures such as an array of arrays or an array of objects.

Promises:

It is a placeholder for a value that isn’t known at the time of the promise is made. It lets for to correlate handlers with the ultimate success value or failure reason of an asynchronous activity. This allows us for asynchronous methods to return values in the same way that uses synchronous methods for to do in; instead of delivering the final value right away, the asynchronous method returns a promise to supply the value at a later time.

Generators:

The generator function can return (or yield) control to the caller at any time. Unlike a standard function, the generator can return (or yield) multiple values on the same need, one after the other.

Proxies:

We can use the Proxy object to establish a proxy for another object that can intercept and redefine its essential activities.

WeakMaps:

In ES6, a new Data Structure or Collection called WeakMap was added. We can add and store a collection of Key-Value pairs with WeakMaps. It has the same Map-like characteristics. The main distinction is that WeakMap keys cannot be primitive data types.

Es6 Sets and Maps:

A set is a collection of elements that are all one-of-a-kind, meaning that no element can be duplicated. In ES6, sets are ordered, and the set’s elements can be iterated in the insertion order. In addition, it accepts any type of value, whether primitive or objects, that can be stored in a set.

A Map object always remembers the true insertion order of the keys. A Map object’s keys and values might be primitives or objects. It gives you a new or empty Map.

Es6 new features Examples

Different examples are mentioned below:

Example #1

Code:

<!DOCTYPE html>
<html>
<body>
<p id="one"></p>
<script>
class Mnths {
constructor(name, sno) {
this.name = name;
this.sno = sno;
}
}
const x = new Mnths("January", 1);
document.getElementById("one").innerHTML =
x.name + " " + x.sno;
</script>
</body>
</html>

 Output:

ES6 New Features output 1

In the above example, we used classes and their features like creating objects and called it on the dom elements.

Example #2

Code:

<!DOCTYPE html>
<html>
<body>
<p id="one"></p>
<script>
function mthd(x) {
document.getElementById("one").innerHTML = x;
}
let y = new Promise(function(p, q) {
let z = 0;
if (z == 0) {
p("Success");
} else {
q("Failure");
}
});
y.then(
function(value) {mthd(value);},
function(error) {mthd(error);}
);
</script>
</body>
</html>

Output:

ES6 New Features output 2

In the second example, we used the promises feature and its functionalities for to implement the application in the es6 scripts.

Conclusion

In general, ECMAScript 2015, often known as ES6 or ES2015, was released with more features and its merits. The next version of ECMAScript would then take over some time to implement with the new advanced features. However, it has many exciting features that include and do not change the original functionality.
