One vital word: “Display mistakes in browser” is perfect used along the debug log, no longer in its place for it. It’s nice for fast iteration for your personal native atmosphere, however you’ll wish to stay it off on any website that’s shared with purchasers — it may well divulge delicate trail knowledge or inside good judgment within the web page output.

Higher debugging, quicker fixes

Those two options deal with other portions of your native debugging workflow:

• The debug log will provide you with a light-weight option to catch mistakes and warnings as they occur.
