Javascript For Loop and While Loop | Javascript Tutorial For Beginners
In this video series we are going to learn modern javascript from scratch. This video is recommended for anyone wanting to learn javascript the modern way with ES2015. No previous programming knowledge is required, so this video series will help you learn javascript as your first programming language.
We are going to take a look on how to create a foor loop, the modern and easy way using ES6. Another loop we can use is a while loop that takes a condition and it is going to run until the statement inside the while loop becomes false.
Things covered in this video:
How to create a for loop in javascript.
How to create a while loop in javascript.

I know I’m late, but as a beginner coder, I would say this is the most concise tutorial to follow. Thank you so much for making this 🙏

Hey did you end up getting a job in the field? I’m currently struggling with my own bootcamp and am skeptical about things improving honestly.

For those of you who got 'Uncaught TypeError: Assignment to constant variable' by copying his code, you need to add 'let' in front of name. The const is causing issues, because the array is declared as a constant and the name must be declared with 'let'. I am surprised he didn't get this error. If there is another way, I would be happy to know!

Hi Ed, can you please explain the differences between for(let i = 0;.. vs for(i = 0;..? Why and when should I add a variable and when should I not? Thank you.

@adityakotian007 5 жыл бұрын

if you have declared the variable outside the loop you don't need to declare it inside. So in this example for(let i=0) if you have declared that there is a variable name i inside the loop. you could have also written let i; // now you are declaring the in the start for(i=0;i

THANK YOU. THIS IS THE BEST TUTORIAL

@chriscorte6902 3 жыл бұрын

well a lot of comments here seem to be thankful but I had no clue what you were talking about. it felt like you just started coding and didn't explain very well what you were doing. For example I didn't know why you created an array of strings, what an "of" statement is, or why you declared the "name" variable ahead of time. Then again, I might just not know enough yet. you explained the "===" operator very well but even then I had no idea why that worked because you declared NAMES, not NAME. you know, with an S. you do have a playlist for "JavaScript For Beginners" so you might just be pulling from that source.

it gets false FROM 100, not 101 because the inequality is strict.

I think that javascript executes the code line by line but in the case of while loop without knowing the updation whether it is incremented or decremented how is it processing the code inside it? please solve my doubt here I stopped my JS course out there...

@klaingarjosue 4 жыл бұрын

beginner here, I had no problem running the code but I'd like to understand. You did loading++ at 6:16 , which makes loading's value go from 0 to 1. 1 is still < 100. So why does it work? I don't get how the value of loading is now more than 100

@chrisparsons289 2 жыл бұрын

You've probably figured it out by now... but because loading++ is within the loop, after it confirms the condition is false it will go through the loop and then add 1 to the value of loading. It will do this over and over again (check the condition to see if it is true, if it is it will then add 1 to loading) until loading value = 100 at which point the loop will stop. This is because 100 is not less than 100 which makes the condition false, therefore stopping the loop.

@sergiuszrozycki 4 жыл бұрын

You need to start from let loading = 0; then it will make 100 times to stop a loop.

@adamabusamra2447 4 жыл бұрын

Really appreciate you trying to explain the concept but to be honest, the video wasn't well structured. you jumped straight to ' for of ', you didn't even mention that it could be used without 'of' like -for (statement 1; statement 2; statement 3) - and then moved on to while loop and didn't even explain the syntax and the difference compared to 'for loop' and why use either one.
