samuelmarina/is-even Compatibility Code for Golang.
Support Range: 0 - 9,999
I thought the is-even library was so great that I tried to port it to the Go language. However, I have only one complaint about this code. it is very hard to write the code by hand. Therefore, I decided that a great solution would be to generate the code automatically!
Note: The range can be changed, but on my machine, if there was too much code, the build was too slow to work...
