Array length in JAVASCRIPT
We use the word length after the array name and a period . to get the number of elements in an array.
JavaScript
const tasks = ["dishes", "windows", "vacuum"];
console.log(tasks.length);
No matter how many elements there are in an array, length will count them for us.
JavaScript
const tasks = ["dishes", "windows", "vacuum", "dusting", "laundry"];
console.log(tasks.length);
