Solves a big problem in javascript specially because in javascript there are no built-in functions
for form validation. Then Regular Expression comes to help you. Main theme is when you want to check
a certain type of pattern say finding only digits or valid email address, then you have to write a
pattern in which all that condition must satisfy. you can check any pattern like validating email ID,
phone nos, credit cards nos, text, numbers. I thing regular expression used in many languages like java,
php, ruby, perl & more.
