Looping Through Arrays in JavaScript
Just like in Java, you can utilize a for loop to iterate through the elements in an array in JavaScript.
Looping Options:
There are three primary options for looping through an array in JavaScript:
Sequential for loop:
Example:
var myStringArray = ["Hello", "World"]; var arrayLength = myStringArray.length; for (var i = 0; i < arrayLength; i++) { console.log(myStringArray[i]); // Outputs: Hello, World }
forEach loop:
Example:
myStringArray.forEach((x, i) => console.log(x)); // Outputs: Hello, World
for...of loop:
Example:
for (const x of myStringArray) { console.log(x); // Outputs: Hello, World }
