Is there any debug tool for Edge?
Yesterday I spent 1 h to find a misspelled function call. The error I got from Chrome console was not helping at all.
A simple message like "undefined xxx on line x" would have helped a lot. In Chrome you get just "error" and a link to a totally unreadable code block.
Use the console.
or firebug in Chrome and FF for example.
There's a very simple syntax checker, but it will not find a miscalled function. Your best bet is to use one of the web consoles, which may throw an error if you call a function that doesn't exist.
