which was introduced in es6 release of javascript

ECMAScript 6 (ES6) is a version of the ECMAScript standard that was released in 2015. It introduced several new features and improvements to the JavaScript language. Some of the notable features introduced in ES6 include:

  1. let and const: These are new ways to declare variables in JavaScript. let allows you to declare variables that are block-scoped, while const allows you to declare variables that are read-only.
  2. Arrow functions: These are a shorthand syntax for creating functions in JavaScript. They have a shorter syntax and do not bind their own this value.
  3. Classes: ES6 introduced a class syntax for creating objects and defining methods, which provides a more familiar syntax for programmers coming from other languages.
  4. Modules: ES6 introduced a module system for organizing and sharing code between different files and modules.
  5. Promises: ES6 introduced a new way to handle asynchronous operations in JavaScript using Promises, which provide a cleaner and more flexible way to handle asynchronous operations.
  6. Template literals: ES6 introduced a new syntax for creating string templates, using backticks (“) instead of single or double quotes. Template literals can include placeholders for expressions and support multiline strings.

These are just a few examples of the new features and improvements introduced in ES6. There are many more features and improvements included in the standard, which you can read about in more detail in the ECMAScript documentation.

  1. Enhanced object literals: ES6 introduced several enhancements to object literals, including support for computed property names, shorthand property names, and shorthand method names.
  2. Spread operator: The spread operator (…) allows you to expand an array or object into a list of elements or properties. It can be used in a variety of contexts, such as in function calls, array literals, and object literals.
  3. Default function parameters: ES6 allows you to specify default values for function parameters, which can be useful for functions that are called with missing or undefined arguments.
  4. Rest parameters: The rest parameter syntax allows you to capture an indefinite number of arguments as an array. It is similar to the spread operator, but the rest parameter syntax is used in the function definition rather than in the function call.
  5. Destructuring: ES6 introduced destructuring, which allows you to extract values from arrays or objects and assign them to variables using a concise syntax.
  6. Symbol type: ES6 introduced the Symbol type, which represents a unique and immutable identifier. Symbols can be used as keys in object properties and can be used to create object-oriented patterns, such as enumerations and singletons.

These are just a few examples of the new features and improvements introduced in ES6. There are many more features and improvements included in the standard, which you can read about in more detail in the ECMAScript documentation.
