how to delete an element from an array in javascript

var arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0];for( var i = 0; i < arr.length; i++){ if ( arr[i] === 5) { arr.splice(i, 1); }}//=> [1, 2, 3, 4, 6, 7, 8, 9, 0]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"]// remove element at certain index without changing original
let arr = [0,1,2,3,4,5]
let newArr = [...arr]
newArr.splice(1,1)//remove 1 element from index 1
console.log(arr) // [0,1,2,3,4,5]
console.log(newArr)// [0,2,3,4,5]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"]["bar", "baz", "foo", "qux"]list.splice(0, 2) // Starting at index position 0, remove two elements ["bar", "baz"] and retains ["foo", "qux"].var arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0];var removed = arr.splice(2,2);/*removed === [3, 4]arr === [1, 2, 5, 6, 7, 8, 9, 0]*/
