I had to create a small function which would replace values in strings. It had to be fast and simple. Before this I had never used regular expressions and now after some research I made a simple regex which would match any number or string between curly braces.
In my opinion, it’s a pain to check if any of node packages has any updates or not. As I use Bower package manager every day, I've realised that a node package, Bower, has better update checking for its own packages than node has for its packages.
