for loop on a array
var array = [1, 2, 3, 4, 5];
// made an array
for (var i = 0; array[i]; i++) // browse your array with this simple condition on index
console.log('element '+i+' = '+array[i]);
//output:
element 0 = 1
element 1 = 2
element 2 = 3
element 3 = 4
element 4 = 5how to cycle through an array js
// Requiring the lodash library
// src: https://lodash.com/docs/4.17.15#forEach
// console: npm i --save lodash
const _ = require("lodash")
// Use of _.forEach() method
_.forEach([1, 2], function(value) {
console.log(value)
});
// => Logs `1` then `2`.
// traversing an object
_.forEach({ 'a': 1, 'b': 2 }, function(value, key) {
console.log(key)
})
// => Logs 'a' then 'b' (iteration order is not guaranteed).

function logArrayElements(element, index, array) {

// logs:
// a[0] = 2
// a[1] = 5
