In this JavaScript walkthrough we look at Codecademy's Loop section, the lesson is "Looping through Arrays" and the video's title is, "Looping Through Arrays Explained, How to Loop through an Array with JavaScript, on Codecademy, Loops". In this lesson, we see how to use a for loop to loop through an Array. We learn that to loop through an array with JavaScript we need to use the array's .length property within its condition. We learn that it is a convention (means common but not necessary) to name your iterator variable i (short for index) to keep track of where in our array we are. We start our iterator at 0 and we are able to target each item in our array by incrementing "i" by 1 each time our condition is true. We are able to loop through an array with javascript nicely using a for loop and understanding how to use a for loop to iterate through an array is extremely powerful for any developer to understand. Make sure to practice for loops, and practice looping through arrays before continuing onto the next lessons. Being able to loop through an array in programming is a key concept to understand if you want to master JavaScript, and master programming altogether!
