iterate through an array code example
Example 1: javascript iterate array
let array = ['Item 1', 'Item 2', 'Item 3'];
// Here's 4 different ways
for (let index = 0; index < array.length; index++) {
console.log(array[index]);
}
for (let index in array) {
console.log(array[index]);
}
for (let value of array) {
console.log(value); // Will log each value
}
array.forEach((value, index) => {
console.log(index); // Will log each index
console.log(value); // Will log each value
});
Example 2: javascript code to loop through array
var colors = ["red","blue","green"];
for (var i = 0; i < colors.length; i++) {
console.log(colors[i]);
}
Example 3: iterate through array javascript
const array = ["one", "two", "three"]
array.forEach(function (item, index) {
console.log(item, index);
});
Example 4: javascript loop through array
var colors = ["red","blue","green"];
colors.forEach(function(color) {
console.log(color);
});
Example 5: how to iterate array in javascript
array = [ 1, 2, 3, 4, 5, 6 ];
//set variable//set the stop count // increment each loop
for (let i = 0; i < array.length ;i++) {
array[i] //iterate through each index.
//add the intructions you would like to perform.
// add any method to array[
}
Example 6: iterate through an array
var arr = [1,2,3,4,5,6,7,8];
// Uses the usual "for" loop to iterate
for(var i= 0, l = arr.length; i< l; i++){
console.log(arr[i]);
}
console.log("========================");
//Uses forEach to iterate
arr.forEach(function(item,index){
console.log(item);
});
