Iterate through an Array with a For loop help please

JavaScript
1

Struggling with this one. I presume my for loop will iterate through the array but I don’t know how to access the values in the array to add them together as a sum.
As a complete beginner I don’t know how you guys do all this!

My code is below;

var myArr = [ 2, 3, 4, 5, 6];

// Only change code below this line
var total = 0;
for (var i = 0; i < myArr.length; i++) {
total = total + myArr[];
console.log(total);
}
]

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

Note: Backticks are not single quotes.

You’re missing something important here. Can you figure out what it is?

Got it! " myArr[i]". Thank you so much.

So next time code like this…

Thank you for helping me with my etiquette on the forum too.

Easy mistake to make. You’ll get good at finding typos soon.
