String Concatenation

Joining strings

Use the + operator to concatenate strings:

first := "Hello"
second := "World"
result := first + " " + second  // "Hello World"

You can also use += to append:

s := "Hello"
s += " World"  // s is now "Hello World"

For joining many strings, this creates many intermediate copies. Use strings.Builder for better performance when building large strings.
