}how 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).
//////////////// To not use lodash ////////////////

function logArrayElements(element, index, array) {
console.log("a[" + index + "] = " + element)
}
[2, 5, 9].forEach(logArrayElements)
// logs:
// a[0] = 2
// a[1] = 5
// a[2] = 9Copyright © 2021 Codeinu
