Useful Regular Expression Tutorial
Hello,
I recently started coding in javascript.
I came across "Regular Expressions" while I'm searching (goolgling) to validate forms (name, email ID's, etc.)
Can someone help this newbie coder by explaining:
- What are regular expression?
- How are they useful in programming?
- Are they simple to understand?
- Where can I get some good reference to learn these?
Any help is much appreciated.
Thank you!
