Regular expressions: understanding greedy versus lazy quantifiers

Imagine this situation:

a = 'one\\two\\three.txt';

The desired output is "three.txt". However, the attempted solution of:

a.match(/\\(.+?)$/)

is unsuccessful. What could be causing this issue? How can we successfully obtain "three.txt"?

Answer №1

Here is a helpful regex to use: [\w.]+?$
