Working with Text

Enemy 1 of 5

Strings and concatenation

A Go string is technically a read-only sequence of bytes, most often holding UTF-8 encoded text — but for everyday use, you can think of it the same way you think of strings in any other language: a piece of text in quotes.

Two strings are joined together with the same + operator used for adding numbers; Go determines from the operand types whether + means numeric addition or string concatenation. Because Go strings are immutable (they can't be changed in place), greeting + name always produces a brand-new string rather than modifying greeting itself.
