JavaScript Best way to combine string + int + string?

[EkBass]

Hi.

I have a set of images i want to load on array. Kind of sprite stuff.

path = img/plr/
path = img/zombie/

or something like that depending of character.

Filename itself is form "Run0.png", "Run1.png" etc.

So, to not to write couple hundreds of lines i thought to use loop.

imgFile = path + 'Run' + i.toString + '.png'
imgFile = path + 'Jump' + i.toString + '.png'

And it does not work. I tried with concat, but when using multiple strings and integer on its call, i got error message that right bracket was expected.
In basic languages and C# using string + int + string results a string but i guess im bit lost with JS now.

What is the proper way to do this? Im working with p5.js here if that counts.

Try adding the parentheses:
imgFile = path + 'Run' + i.toString() + '.png'

You don't even need to use toString() here. Variables you append to a string are converfted to string automagically.

hmmm...i copied code from p5 online editor to my own computer and all works out. So yes, string + int + string does the job
