How Can I Iterate Through a JavaScript Array?

How to Loop through an Array in JavaScript

In Java, you can traverse an array by iterating through each element using a for loop. This loop syntax is as follows:

for (String s : myStringArray) {
    // Do something
}

Is there a similar way to loop through an array in JavaScript?

Answer:

Yes, there are several ways to loop through an array in JavaScript. Here are three common options:

1. Sequential for loop:

var myStringArray = ["Hello","World"];
var arrayLength = myStringArray.length;
for (var i = 0; i < arrayLength; i++) {
    console.log(myStringArray[i]);
    //Do something
}

2. forEach() method:

xs.forEach((x, i) => console.log(x));

3. for...of loop:

for (const x of xs) {
    console.log(x);
}

These examples demonstrate different ways to iterate through an array in JavaScript. Each approach has its own advantages and uses, depending on the specific requirements of the task.
