The go function is called twice


The go function has a syntax error


The go function has been defined twice


go is not a command that Karel understands

Answer 1

The go function has been defined twice.

Explanation: JavaScript allows duplicate function declarations, but the second definition overwrites the first, which is almost certainly a mistake here. It's not a syntax error, calling go() twice is fine, and go is a user-defined function (not a built-in Karel command).

Fixes: remove the duplicate definition, or rename one of them (and call the correct name), or combine their logic into a single go function.
