JavaScript for Beginners #12 - For Loops

In this beginner javascript tutorial I will be discussing for loops. For loops are one of the most commonly used block of code in javascript and are extremly important to understand. They are commonly used to loop through structures like arrays and to increment a counter. I will show examples of both in this video.

It's crazy that if you know basic programming in any language, you can literally just go to Tim's YouTube channel, watch a few videos, and then just straight up learn a new language. This man has taught me Python, Java, and Javascript. He's the GOAT for sure!

Tim - Your videos are great! Some of the best beginner tutorials out there! You should have many more views.

4:49 OK, in Python, we do
*value in arr*
That's it.
That's really it.

if anybody dosen't know, the syntax for using exponents is 'n ** 2', where n is a variable, and 2 is the exponent

It`s getting more and more interesting!

6:24 i am not sure, but i think you can use 'value in arr' instead of using a loop

[CM_Burns]

so you're saying for each time the outer loop will execute, the inner loop executes n times

[agokn]

why you should add "arr" in function findInArray(arr, value), you can just write only "value" there and is makes more sense I think, and it still works.. can you explain why you wrote "arr" there ?

[adarshcj]

Is it needed to learn all loops. I had only know for loop is there any problem

[valeriaalfonsotobon]

I was doing all find until now, I would like to know what's the real purpose of loops. Still, your videos are great. Maybe someone can recommend me a math channel!

[not_vinkami]

So how do we do
*for element in list_a:*
*func(element)*
in JavaScript?
*for (var i = 0; i < list_a.length; i++){*
*func (list_a[i])*
If that's really it then js sucks

[kanui]

Hi, Tim!
I wanna ask to you, how to send data from javascript to python (and back again)?

[sharriceowens]

ok you had me understanding everything until this video..im lost.
