JavaScript

why does return Math.random(); work if this can in fact return 0 ?

function randomFraction() {

// Only change code below this line

return Math.random();

// Only change code above this line
}

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.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

HI @vincentlomeli !

Welcome to the forum!

Math.random can return 0 but it can also return random numbers like these
0.5064617727895493
0.9723828818312354
0.9860885763648548
0.8611045893904035

The goal of this exercise is to generate a new random number every time the function is called.

If you just leave it at 0 then it will only return 0 every time.

Thank you. I was confused because the exercise ask to generate a random number “not 0” and the solution can in fact return 0. Again, thank you for taking the time to help.
