Code not compatible ?

Question

So let's say that in python I have this function called rotate_90(m) that will take a matrix m and rotate its terms 90 degrees clockwise. Now if I want to make the function rotate_270(m), knowing that 270=9*3 I'll do:
def rotate_270(m):
for i in range(3):
m=rotate_90(m)
return m
Now let's say I have this same function rotate_90(m) but in javascript. If I try to do
function rotate_270(m){
for(i=0;i!=3;i++)
m=rotate_90(m)
return m
}
For some reason it doesn't seem to work....
Could somebody tell me why please ?

Answer 1

maybe try:
for( var i=0; i < 3; i++)
m=rotate_90(m)

I don’t think this will fix the problem though, it should just make i a local variable, but maybe that’s the issue?

Answer 2

Indeed I tried with for(let i=0;i!=3...etc) and it worked ! Thank you Jackson O’Donnell !

Answer 3

Jackson O’Donnell sorry my question wasn't clear....
So in python it works but not in javascript: in javascript I believe that it runs forever because if I alert the output, that alert will never show up...

Answer 4

is the rotate_90(m) written in JS as well? It may be an issue in that function. And what is your error? Does it just not run? Run forever? Wrong output?
