Arrow function in javaScript

When ES6 (ECMAScript 2015 or ECMAScript 6) came into the role, It was a major revision in javaScript and introduces new syntax.

One of these syntaxes was Arrow Function. Arrow function syntax introduces new ways to write a function, The way made code less and easy to write and readable too, we don't need to write function and return keywords for a single expression.

Without using Arrow function

Using Arrow function

Now let's see what's happens with a single line of code in Arrow Function.

So, The differences in the Arrow function are?

• There are no parentheses with parameters.
• There are no curly braces for the function body.
• The syntax is easy to write and read.
• return keyword is not required for a single expression.

Syntax for Arrow Function

Some importants points

• No parentheses require for a single parameter
• no return keyword require or a single expression
• return keyword require for multiple expression
• parentheses require for multiple parameters.
