[Solved] Why doesn't the following Regular Expression detect '.'?

Question

I am trying to validate email input using the REGEX as follows:

/^[a-z][a-z0-9]+@[a-z]\./

For some reason i have issues with detecting the dot in the string..Can anyone help me with the correction.

i know it's quite basic REGEX but i'm still practicing REGEX..

Answer 1

$hardul B after \. [a-z]{2,3}$ this was missing. It is necessary to put because we write com, in, co after dot (.) and also here the size of String maybe be 2-4 after dot(.) so we need to use {2,4}. Here $ used to match the String
