Chrome 10 javascript trap with variable named ‘performance’

leave a comment »

Just a quick reminder.

Don’t name any of your own javascript variables ‘performance’. Chrome uses this variable internally for its developers toolbox. I used it to measure my own performance metrics which worked perfectly in any other browser, but testing Chrome 10 revealed strange results. In the end I discovered that Chrome 10 used it for its own measurements which made my efforts useless, at least the way I wanted to use the variable.
