Is the string type in Go mutable or immutable?

In Go, the string type is immutable. This means that once a string is created, its contents cannot be changed. Any operations that seem to modify a string actually create a new string.

For example:

s := "hello"
s = s + " world" // a new string is created, the original "hello" remains unchanged

This behavior ensures safety and simplicity when working with strings, but it is important to consider that frequent concatenations can be less efficient than working with mutable buffers, such as bytes.Buffer."}]}]}
