for each array object javascript 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: forEach
const arraySparse = [1,3,,7]
let numCallbackRuns = 0
arraySparse.forEach((element) => {
console.log(element)
numCallbackRuns++
})
console.log("numCallbackRuns: ", numCallbackRuns)
// 1
// 3
// 7
// numCallbackRuns: 3
// comment: as you can see the missing value between 3 and 7 didn't invoke callback function.
