I am trying to create a regular expression that checks for letters, numbers, and underscores. In .NET, I can do “^\w+$”. However, I am not that familiar with the JavaScript syntax. Can somebody help me out?
Thank you!

One obvious difference is that in JavaScript, you write the regex as
/pattern/flags— this is Perl-style. Your “example” would then be^\w+$→/^\w+$/.For example, replace multiple
e‘s with onee, case-insensitive search (hence theiflag):Returns:
qwerty.
