All Things JavaScript

Concepts

  • this
  • bind
  • Hoisting
  • Operator Precedence
  • Lambda
  • Object literals
  • Prototypical inheritance vs. classical inheritance
  • Prototypical inheritance: objects inherit from other objects; class free
  • Differential inheritance
  • proto, delegation
  • Object.create
  • new operator: required when calling constructor function
  • Power constructors
  • Immediately-Invoked Function Expression (IIFE); self-invoked functions
  • Regular Expressions
  • Declarative vs imperative
  • Closures
  • Loose typing
  • Dynamic objects
    • Object hardening (freeze)
  • Truthy, Falsy
  • Phony arrays
  • CORS
  • "use strict"
    • Treats some mistake as errors
    • Silent failures thrown as errors
    • Use within function to avoid concatenation problems
    • Forces use of explicit "var"
    • Keeps vars created by eval within evaluated code
    • Prevents/throws on:
    • accidental creation of globals
    • assignments to non-writables (NaN, getter-only property, new property on non-extensible object)
    • deleting undeletables
    • duplicate property names
    • duplicated argument names
    • octal syntax (leading zero prefix on numbers)
    • with
  • Type coercion - prevented with ===
  • typeof
  • 0.1 + 0.2 !== 0.3
  • IEEE floating point problem
  • for...in
  • Does deep dredge instead of shallow skim
  • Deep members must be explicitly filtered (obj.hasOwnProperty(prop))
  • XSS
  • Separation of concerns
  • Learning JavaScript Design Patterns
  • Pro JavaScript Design Patterns
  • Learning Javascript with Object Graphs
  • AOP
  • Interceptors
  • Promises, events
  • tildeio/rsvp.js
  • kriskowal/q
  • Pub/sub
  • https://github.com/postaljs/postal.js
  • Call vs. apply
  • Function declaration vs. function expression
function step(){}
var step = function() {}
