}Iterate Through All an Array’s Items Using For Loops
function filteredArray(arr, elem) {
let newArr = [];
// change code below this line
for (let i = 0; i < arr.length; i++) {
if (arr[i].indexOf(elem) == -1) {
//Checks every parameter for the element and if is NOT there continues the code
newArr.push(arr[i]); //Inserts the element of the array in the new filtered array
}
}
// change code above this line
return newArr;
}
// change code here to test different cases:
console.log(filteredArray([[3, 2, 3], [1, 6, 3], [3, 13, 26], [19, 3, 9]], 3));Iterate Through an Array with a For Loop
var arr = [10, 9, 8, 7, 6];
for (var i = 0; i < arr.length; i++) {
console.log(arr[i]);

}Iterating or loop through the elements of an array is with a for loop (for):
var keys = Object.keys(o); // Get an array of property names for object o
var values = [] // Store matching property values in this array
for(var i = 0; i < keys.length; i++) { // For each index in the array
var key = keys[i]; // Get the key at that index
values[i] = o[key]; // Store the value in the values array
}Iterate over all the items in array of arrays
for( var i = 0, len_i = json.length; i < len_i; i++ ) {
for( var j = 0, len_j = json[ i ].length; j < len_j; j++ ) {
// do something with json[ i ][ j ]; (the value in the inner Array)
}
