Regular Expression question

Hello

I am doing a javascript homework,

i am asked to write a reg to validate a password like this:

start with 4 or more letters, end with 2 or more digits

 

so i wrote this

return /^\w{4,}\d{2,}$/.test(text);

 

is it correct?

when testing the application i write abcd12 as password but it doesn't work,

plz help

thank u

The only thing I technically see "wrong" with it is that \w matches more than just letters. It also matches numbers and underscores.  Also \d technically will match more than straight numbers.  But other than that, that should return true as expected, at least for "abcd12".  To be more explicit you should use

 

return /^[a-zA-Z]{4,}[0-9]{2,}$/.test(text);

 

 

Perhaps you should first explain what "it doesn't work" means to you, and also perhaps show some more code....is that all of your (relevant) code?
