Difference between console.log() and console.debug()?

Technically console.log console.debug and console.info are identical However the way they display the data is little different. console.debug is not visible by default in the browser's JS console. It can be enabled by using the console's filter options.

console.log Black color text with no icon

console.info Blue color text with icon

console.debug Pure black color text

console.warn Yellow color text with icon

console.error Red Color text with icon

var playerOne = 120;
var playerTwo = 130;
var playerThree = 140;
var playerFour = 150;
var playerFive = 160;

console.log("Console.log" + " " +  playerOne);
console.debug("Console.debug" + " " +playerTwo);
console.warn("Console.warn" + " " + playerThree);
console.info("Console.info" + " " + playerFour);
console.error("Console.error" + " " + playerFive);

For at least IE, Firefox and Chrome consoles, .debug() is just an alias for .log() added for improved compatibility
