Regular expression brief notes

Greedy vs lazy evaluation

/<div>.+</div>/
This will not match <div>text</div> because .+ consumes </div> characters. .+ uses greedy evaluation.
/<div>.+?</div> This will match <div>text</div> because .+? uses lazy evaluation and returns control to next expression as it finds first match.
