Printing all ASCII characters in Javascript

Question

I need to do something like this:

1. Have a variable of some type.
2. Run in a loop and assign all the possible ASCII characters to this variable and print them, one by one.

Is something similar possible for UNICODE also?

Solution

I'm not sure how exactly you want to print, but this will console.log printable ascii

for(var i=32;i<127;++i) console.log(String.fromCharCode(i));

You can document.write then if that's your intention. And if the environment is unicode, it should work for unicode as well, I believe.

No font contains all Unicode characters (even font technology currently prevents that). On the other hand, rendering engines may use different fonts – e.g., web browsers generally use some fallback fonts.

what about extended ascii?

It basically works with whatever encoding the interpreter uses. You may need to change range in the for loop, though ;-)

Array.from(Array(127).keys()).slice(32).map(a => String.fromCharCode(a)) in one expression to get the array of them all. With zeroTo function it gets shorter, zeroTo(127).slice(32).map(a => String.fromCharCode(a))
