This is an interesting feature of Javascript that allows to shorten code, make it easier to read and simple
Lets declare the array colors first:
let colors = [‘white’, ‘red’, ‘blue’];
Here is an example of forEach function:
colors.forEach(function (color){
console.log(color)
});
Now with arrow function:
colors.forEach(color => console.log(color));
More examples to understand better:
function sum(m, n){
return m+n
}
With Arrow Function:
let sum = (m,n) => m+n;
function isPositive(num){
return num ≥=0;
};
With Arrow Function:
let isPositive = num => num ≥=0;
function randomNumber(){
return.Math.random;
};
With Arrow Function:
let randomNumber = () => Math.random;
