loop through an array javascript
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 value in array
}
array.forEach((value, index) => {
console.log(index); // Will log each index
console.log(value); // Will log each value
});javascript loop through array
const myArray = ['foo', 'bar'];
myArray.forEach(x => console.log(x));
//or
for(let i = 0; i < myArray.length; i++) {
console.log(myArray[i]);
}for array javascript
let iterable = [10, 20, 30];
for (let value of iterable) {
value += 1;
console.log(value);
}
// 11
// 21
// 31javascript for of
const array = ['hello', 'world', 'of', 'Corona'];
for (const item of array) {
console.log(item);
}use these instead of a for loop javascript
const array = [1, 2, 3];array.forEach(function(elem, index, array) { array[index] = elem * 2;});console.log(array); // [2,4,6]mdn for..of
function* fibonacci() { // a generator function
let [prev, curr] = [0, 1];
while (true) {
[prev, curr] = [curr, prev + curr];
yield curr;
}
}
for (const n of fibonacci()) {
console.log(n);
// truncate the sequence at 1000
if (n >= 1000) {
break;
}
