I tried above solution but it is not working. Currently I have

function convertText(command, converter) { for (prop in command) { if (instanceOf(command[prop], String)) { command[prop] = converter(command[prop]); } } }

When I try to save recorded script, getting following error:

error: ReferenceError: instanceOf is not defined.

If anyone have solution please share with me. Thanks a ton.
