Ruby #tap method
Ruby Object#tap method is a pretty cool method that can improve the readability of your code.
tap was introduced in Ruby 1.9, what it does is pretty simple: it yields a value to a block and then returns it.
It’s especially useful when you need to populate an hash or a variable and return the value, it allows you to cut those intermediate variables.
For example you can turn this:
Liquid error: No such file or directory - posix_spawnp
into this:
Liquid error: No such file or directory - posix_spawnp
In my opinion, the second example is much better, it is easier to read and parse rapidly.
