forEach on js object\ code example
Example 1: js for each item do
let array = ['Item 1', 'Item 2', 'Item 3'];
array.forEach(item => {
console.log(item); // Logs each 'Item #'
});
Example 2: javascript foreach object
function logArrayElements(element, index, array) {
console.log('a[' + index + '] = ' + element)
}
// Notice that index 2 is skipped, since there is no item at
// that position in the array...
[2, 5, , 9].forEach(logArrayElements)
// logs:
// a[0] = 2
// a[1] = 5
// a[3] = 9
