filter

The filter() method is used to iterate over each element of an array and filter among them with conditions.

Syntax

array.filter()

Example

const numbers = [1,2,3,4,5,6,7,8,9];
const evenNumbers = number.filter((element) => {
  if(element%2 === 0) {
		return element;
	}
});
console.log(evenNumbers)
/* Prints
  [ 2, 4, 6, 8 ]
*/

We can see that the filter() loops over each element of the provided array, and applies conditions to return the required value.
