You have four options here:

  • Play will begin running the code.
  • Step over and Step into execute the next line of code. If the next line of code is a function call, Step over will execute the entire function and stop at the next line of code outside it. Step into will stop at the first line of code inside the function.
  • Use Step out if you are inside a function, and want to move on to the next function.
