The for-of loop is a modern way to iterate over iterable objects in JavaScript, such as arrays, strings, and even generator functions. It simplifies the process of accessing each item in a collection.
When you use the for-of loop with arrays, it directly accesses each item without needing to manage an index. For example, if you have an array of fruits like let fruits = ['apple', 'banana', 'cherry'];, you can loop through each fruit with for (let fruit of fruits) { console.log(fruit); }. This loop automatically handles the iteration and gives you each item in the array directly.
Strings, which are sequences of characters, can also be iterated using the for-of loop. For instance, with the string let word = 'hello';, you can access each character using for (let char of word) { console.log(char); }. This loop goes through each character in the string, making it easy to work with individual characters.
