如何轻松检查字符串中的空格数？

Question

Basically for every letter in a string I will be increasing an integer by 1. The string length function would work perfectly, but it will include spaces as part of the length. I only want the number of characters in a string, not including spaces.

How can you check how many spaces a string has? I could then subtract that value from the string.length .

yourString.replace(/\s/g, "").length
