Lesson 11 / 27

Strings and runes

Q: How should you learn Strings and runes?

Run one focused example and inspect the result.. Small experiments reveal cause and effect.

Explain Strings and runes, test a small program, and use the result to build confidence.

The essential idea

Strings and runes becomes clear when you identify its job before memorising syntax. In Go, small explicit pieces combine into programs that are easy to read, build, and change.

Run a tiny experiment

Keep the path from source file to compiled program in mind as you learn this part.

// Explore strings-runes with one small program.
value := 0
fmt.Println(value)

Output:

A useful habit

Do not copy a solution blindly. For Strings and runes, change one value, run go test or go run, and explain why the result changed.
