How to return a string value from a Bash function

I'd like to return a string from a Bash function.

I'll write the example in java to show what I'd like to do:

public String getSomeString() {  return "tadaa";}String variable = getSomeString();

The example below works in bash, but is there a better way to do this?

function getSomeString {   echo "tadaa"}VARIABLE=$(getSomeString)
