Removing spaces from a variable input using PowerShell 4.0

Question

I\'ve tried a few things already but they don\'t seem to work for some reason.

Basically what I\'m attempting to do is have a user input a value using the \"Read-host\

Answer 1

If the string is

$STR = 'HELLO WORLD'

and you want to remove the empty space between 'HELLO' and 'WORLD'

$STR.replace(' ','')

replace takes the string and replaces white space with empty string (of length 0), in other words the white space is just deleted.
