remove something from an array code example

Example 1: remove a particular element from array

var colors = ["red","blue","car","green"];
var carIndex = colors.indexOf("car");//get  "car" index
//remove car from the colors array
colors.splice(carIndex, 1); // colors = ["red","blue","green"]

Example 2: js array delete specific element

var array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0];
var filtered = array.filter(function(value, index, arr){
    return value > 5;
});
//filtered => [6, 7, 8, 9]
//array => [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]

Example 3: remove in javascript

function arrayRemove(arr, value) 
{
  return arr.filter(function(ele){ 
    return ele != value;
  });
}
//var result = arrayRemove(array, 6);// result = [1, 2, 3, 4, 5, 7, 8, 9, 0]

Example 4: remove element from array javascript

let numbers = [1,2,3,4]

// to remove last element
let last_num = numbers.pop();
// numbers will now be [1,2,3]

// to remove first element
let first_num = numbers.shift();
//numbers will now be [2,3]

// to remove at an index
let number_index = 1
let index_num = numbers.splice(number_index,1); //removes 1 element at index 1
//numbers will now be [2]

//these methods will modify the numbers array and return the removed element
