	console.log(element);
}

javascript best way to iterate over array

[1,2,3,4,"df"].forEach((value, index) => console.log(index,value));
output

2 3
3 4
4 'df'

iterate array in javascrpt

let array = [ 1, 2, 3, 4 ]; //Your array

	//Now element takes the value of each of the elements of the array
	//Do your stuff, for example...
  	console.log(element);
}

Ways to iterate array in js

let arr = ['js', 'python', 'c++', 'dart']

// no 1
for (item of arr) {
	console.log(item);
}

// no 2
for (var item = 0; item < arr.length; item++) {
	console.log(arr[i]);
}

// no 3
arr.forEach(item=>{
	console.log(item);
})

// no 4
arr.map(item=>{
	console.log(item);
})

// no 5
var item = 0;
while (item < arr.length) {
	console.log(arr[item]);
  	item++;
}

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[
} 

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);
});

});

iterate array

    for (let value of array) {
      sum+=value;
    }

iterate array

for (let [key,val] of array.entries()) {

Loop through array

String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
System.out.println(cars[0]);

// Change elements in array
cars[0] = "Opel";
System.out.println(cars[0]);

// Length of array
System.out.println(cars.length);

// Loop through array
for (int i = 0; i < cars.length; i++) {
  System.out.println(cars[i]);
}

loop through array

#include <iostream>
using namespace std;

int main ()
{
   string texts[] = {"Apple", "Banana", "Orange"};
   for( unsigned int a = 0; a < sizeof(texts); a = a + 1 )
   {
       cout << "value of a: " << texts[a] << endl;
   }

   return 0;
}

Iterate Over an Array,

// Task 1
var dairy = ['cheese', 'sour cream', 'milk', 'yogurt', 'ice cream', 'milkshake'];
function logDairy() {
    for (food of dairy) {
        console.log(food)
    }
}

// Task 2
const animal = {
    canJump: true
};
const bird = Object.create(animal);

bird.canFly = true;

bird.hasFeathers = true;

function birdCan() {
    for (value of Object.keys(bird)) {
        console.log(value + ":" + " " + bird[value])
    }
}
// Task 3
function animalCan() {
    for (props in bird) {
        console.log(`${props}: ${bird[props]}`);
    }
}
logDairy();
birdCan();
animalCan()
