You think you know the Chrome Web console?

There is more than console.log() to the Chrome Web Console:

Output debug, info, warnings and errors:

console.debug('Just so that the dev know') 
console​.info('Here is some info') 
console.warn('This may be a problem') 
console.error('This must not happen')

Assert results:

console.assert(nodeList.length < 500, "NodeList is > 500");

Ask for breakpoint in code:

debugger; //yes, that's it, just need to have this keyword on a line.

Output in a table:

console.table([[1,2,3], [4,5,6]]) 
console.table([{a:2, b:3}, {a:4, b:5}])
