Answers for "iterate through all an array's items using for loops"

create a loop that runs through each item in an array

Create a loop that runs through each item in the "fruits" array.

var fruits = ['Apple', 'Banana', 'Orange']

for(x of fruits){
	console.log(x);
}

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]);
}

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)
    }
}
