This leads to much simpler and easy to understand code. I'll quote Terry Davis: + +> An idiot admires complexity, a genius admires simplicity. + +Making a topic look complex is easy, but making it simple and easy to understand is what truly takes skill. Instead of complex and over-engineered solutions that make us "feel intelligent" just because they're complex we should strive for simplicity. + +## Languages + +One of the more unique facts about my life is that I spent 8 years in Asia, more specifically Japan and Korea. This helped me broaden the pool of languages I can utilize to communicate and it also gave me an understanding of the subtle differences between Western and Eastern cultures. + +Currently I speak: +

That is exactly why we are going to define separate rules for alignment. + +### Presentational alignment + +> The proper positioning or state of adjustment of parts in relation to each other. + +Presentational alignment refers to positioning different parts better in relation to each other and does not convey any meaning. It will make the code look better but the whitespace doesn't convey that the code is different from the surrounding code, thus being only used to align parts with each other for presentational purposes. + +```go +type User struct { + // Note how we're using tabs to indent the struct + // and spaces to align the name of the data type. + ID string + Name string + Age int +} +``` + +Alignment should be used _after_ semantic indentation and should be done using **spaces**. The reason is that alignment requires precise positioning on a monospace font and the tab character can't do that because it has dynamic width. + +Your team members will thank you because they can finally change the indentation width to something they like and it won't break the alignment of the code. + +## Conclusion + +Rather than going full tabs or full spaces, consider using a hybrid approach where each character does what it's best at and therefore combining the best of both worlds. I have been using this system for as long as I can remember and I never had a problem with it. For me, this is the de facto standard nowadays and the more people start switching to this system, the better.
