6 different methods to loop through the array
You can loop through an array by many different methods. I have sorted my 6 favorite methods from top to bottom.
1. Using JavaScript for loopJavaScript for loop
When it's to simply loop through an array, the for loop is my first choice.
let array = [1, 2, 3, 4, 5];
for (let i = 0; i < array.length; i++) {
console.log(array[i]);
}2. Using forEach loop
forEach loop is a modern way to loop through the array. Also, it gives more flexibility and control over the array and elements.
let array = [1, 2, 3, 4, 5];
array.forEach((element) => {
console.log(element);
});3. Using for...of
for...of loop gives you direct access to the array elements.
let array = [1, 2, 3, 4, 5];
for (let element of array) {
console.log(element);
}4. Using for...in loop
for...in gives you a key using which you can access array elements.
let array = [1, 2, 3, 4, 5];
for(let index in array){
console.log(array[index]);
}5. Using while loop
while loop is can be used to loop through the array as well.
let array = [1, 2, 3, 4, 5];
let length = array.length;
while(length > 0){
console.log(array[array.length - length]);
length--;
}6. Using do...while loop
Likewise, I use do...while loop
let array = [1, 2, 3, 4, 5];
let length = array.length;
do {
console.log(array[array.length - length]);
length--;
}
while (length > 0)
