Desktop mouse and keyboard controls - Game development
there are no helpers so you have to remember what the given codes are (or look them up); 37 is the left arrow: function keydownhandler(event) { if(event.keycode == 39) { rightpressed = true; } else if(event.keycode == 37) { leftpressed = true; } if(event.keycode == 40) { downpressed = true; } else if(event.keycode == 38) { uppressed = true; } } the keyuphandler looks almost exactly the same as the keydownhandler above, but inst...
...if the left arrow is pressed (⬅︎; key code 37), we can set the leftpressed variable to true and in the draw function perform the action assigned to it — move the ship left: function draw() { ctx.clearrect(0, 0, canvas.width, canvas.height); if(rightpressed) { playerx += 5; } else if(leftpressed) { playerx -= 5; } if(downpressed) { playery += 5; } else if(uppressed) { playery -= 5; } ctx.drawimage(img, playerx, playery); requestanimationframe(draw); } the draw function first clears the whole canvas — we draw everything from scratch on every single frame.
... we could write our own keycode object containing the key codes, for example: var keyboardhelper = { left: 37, up: 38, right: 39, down: 40 }; that way instead of using the codes to compare the input in the handler functions we could do something like this, which is arguably easier to remember: if(event.keycode == keyboardhelper.left) { leftpressed = true; } note: you can also find a list if the different keycodes and what keys they relate to in the keycode reference page.

Redis Tips
ode.js redis client: https://github.com/mranney/node_redis npm install redis python redis client: https://github.com/andymccurdy/redis-py there are some gotchas with the python api: https://github.com/andymccurdy/redis-py#api-reference select statement not implemented del is 'delete' in python zadd argument order is wrong setex argument order is wrong the default redis port is 6379.
... in node, create client with explicit host and port like so: > var r = require('redis').createclient(6379, '127.0.0.1') commands are asynchronous.
... > r.zrevrange('last-login', 0, -1, 'withscores', print); ["lloyd", "1339627441.115", "zcarter", "1339627437.7579999", "jparsons", "1339627432.928"] awesome.

example the content principal above can be made expanded/extended like so: var principal = [gbrowser.selectedtab.linkedbrowser.contentprincipal]; // this is now an expanded (aka extended) principal var sandbox = components.utils.sandbox(principal); null principal you can create a null principal using code like: cc["@mozilla.org/nullprincipal;1"].createinstance(ci.nsiprincipal); from firefox 37 onwards, you can also specify the null principal by simply passing null as the principal argument.

Number - JavaScript
number is a primitive wrapper object used to represent and manipulate numbers like 37 or -9.25.
... a number literal like 37 in javascript code is a floating-point value, not an integer.
...37 is still a number, not a bigint.) number may also be expressed in literal forms like 0b101, 0o13, 0x0a.

Proxy - JavaScript
examples basic example in this simple example, the number 37 gets returned as the default value when the property name is not in the object.
... obj[prop] : 37; } }; const p = new proxy({}, handler); p.a = 1; p.b = undefined; console.log(p.a, p.b); // 1, undefined console.log('c' in p, p.c); // false, 37 no-op forwarding proxy in this example, we are using a native javascript object to which our proxy will forward all operations that are applied to it.
... const target = {}; const p = new proxy(target, {}); p.a = 37; // operation forwarded to the target console.log(target.a); // 37 // (the operation has been properly forwarded!) note that while this "no-op" works for javascript objects, it does not work for native browser objects like dom elements.

Grammar and types - JavaScript

... \0 null byte \b backspace \f form feed \n new line \r carriage return \t tab \v vertical tab \' apostrophe or single quote \" double quote \\ backslash character \xxx the character with the latin-1 encoding specified by up to three octal digits xxx between 0 and 377.

Deprecated and obsolete features - JavaScript
getenumerablepropertykeys (bug 783829, firefox 37) getownpropertynames (bug 1007334, firefox 33) keys (bug 1007334, firefox 33) escape sequences octal escape sequences (\ followed by one, two, or three octal digits) are deprecated in string and regular expression literals.
... string.prototype.quote is removed from firefox 37.

SyntaxError: illegal character - JavaScript
famous examples of this are quotes, the minus or semicolon (greek questionmark (u+37e) looks same).
... “this looks like a string”; // syntaxerror: illegal character // “ and ” are not " but look like this 42 – 13; // syntaxerror: illegal character // – is not - but looks like this var foo = 'bar'; // syntaxerror: illegal character // <37e> is not ; but looks like this this should work: "this is actually a string"; 42 - 13; var foo = 'bar'; some editors and ides will notify you or at least use a slightly different highlighting for it, but not all.

DataView.prototype.setBigInt64() - JavaScript
the highest possible value that fits in a signed 64-bit integer is 2n ** (64n -1n) - 1n (9223372036854775807n).
... upon overflow, it will be negative (-9223372036854775808n).

Date.parse() - JavaScript
if ipodate is an existing date object, it can be set to august 9, 1995 (local time) as follows: ipodate.settime(date.parse('aug 9, 1995')); some other examples of parsing non-standard date strings: date.parse('aug 9, 1995'); returns 807937200000 in time zone gmt-0300, and other values in other time zones, since the string does not specify a time zone and is not iso format, therefore the time zone defaults to local.
... date.parse('wed, 09 aug 1995 00:00:00'); returns 807937200000 in time zone gmt-0300, and other values in other time zones, since there is no time zone specifier in the argument and it is not iso format, so is treated as local.

Function.prototype.bind() - JavaScript
function list() { return array.prototype.slice.call(arguments); } function addarguments(arg1, arg2) { return arg1 + arg2 } const list1 = list(1, 2, 3); // [1, 2, 3] const result1 = addarguments(1, 2); // 3 // create a function with a preset leading argument const leadingthirtysevenlist = list.bind(null, 37); // create a function with a preset first argument.

Leak-hunting strategies and tips
if you really need to debug leaks that involve js objects closely, you can get detailed printouts of the paths js uses to mark objects when it is determining the set of live objects by using the functions added in bug 378261 and bug 378255.

Refcount tracing and balancing
you may use an object's serial number with the following variable to further restrict the reference count tracing: xpcom_mem_log_objects set this variable to a comma-separated list of object serial number or ranges of serial number, e.g., 1,37-42,73,165 (serial numbers start from 1, not 0).
