JavaScript Garden Although JavaScript deals fine with the syntax of two matching curly braces for blocks, it does not support block scope; hence, all that is left in the language is function scope. function test() { // a scope for(var i = 0; i < 10; i++) { // not a scope // count } console.log(i); // 10} There are also no distinct namespaces in JavaScript, which means that everything gets defined in one globally shared namespace. Each time a variable is referenced, JavaScript will traverse upwards through all the scopes until it finds it. JS keyCodes When a KeyboardEvent fires, you can test which key was pressed because that event contains information you can write logic against. document.addEventListener("keydown", function(event) { console.log(event.which); } For example, by pressing "a", you'll get 65. Apparently it's best to write logic against which, as keyCode and charCode are complicated: The event.which property normalizes event.keyCode and event.charCode. It is recommended to watch event.which for keyboard key input.
