Mess up Internet Explorer behaviour with console.log

Using console.log statements in your Javascript code can break behaviour in Internet Explorer, including version 9 of that browser.

I just got burned by this.

So note to self: Remove all instances of console.log() prior to deploying or before testing on Internet Explorer.

  1. You can also add a single line function definition of console.log if it doesn’t exist using a ternary operator. Just an empty function is enough to fix IE and allow you to keep logs in for debugging in the field.
