Do I want to die on this hill?

• Pass: This is morally good and if not handled has long term consequences
• Fail: This if self serving

Am I including everyone?

• Pass: My ego is not driving this conversation
• Fail: The people in this conversation will only tell me I'm right and not push back

Strings

String.prototype.*

None of the string methods modify this – they always return fresh strings.

• charAt(pos: number): string ^ES1

  Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Essential JavaScript Links

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).

JavaScript Static Analysis Tools

Most people are familiar with these three tools:

1. [JSHint][1]
2. [JSLint][2]
3. [Google Closure Linter][3]

The first one is more popular among developers because it is style-agnostic. The other two enforce rules of [Crockford Style][4] and [Google Code Style][5] respectively.
