Unnecessary check of pixels?

[fenderil]

lib/utils.js, string 75
result[key] = value.endsWith('px') ? parseInt(value, 10) : value;

You would get next transform:
String: '4px 4px' -> Number: 4
Btw why did you add this check?

@fenderil Good catch, Thanks!

This was added so we don't need to always strip px to do the calculations in JS (Common use case is spacing variables)
