template literals in javascript
Arrow functions, also called “fat arrows” were introduced with ES6 as a new syntax for writing Javascript functions.
By utilising a token (=>) that looks like a fat arrow, they are a more concise and elegant way of writing function expressions.
Basic Syntax
//ES5 Way
function myFunc() {
//statements here ...
}
//ES6 Way
myFunc = () => {
//statements here ...
}Parentheses in ES6 functions are optional when only one parameter is passed.
myFunc = val => {
return val += 1;
}
alert(myFunc(2)); //3But if no parameters are passed to the function, then parentheses are required.
