All code is guilty until proven innocent.

Program testing can be a very effective way to show the presence of bugs, but is hopelessly inadequate for showing their absence.

• Learning from Code
  • Reading & understanding source code
  • Making small, incremental experiments
  • Copying & modifying others' code
• Using assertion libraries
  • Failed assertions throw errors!
  • Deep equality
  • Strict equality
  • Throws
• Using test reporters
  • describe
  • it
• TDD
  • Trust the tests!
  • Solving challenges one test at a time
• Debugging
  • Reading test results to debug code behavior
  • Interpreting assertion errors

• JS Operators
  • Implicit Coercion
  • Operator Precedence
• Control flow
  • for in, for of
  • break, continue
• Reference vs. Value
  • Comparing arrays & objects
  • Avoiding side-effects
• Arrays
  • Reading & writing entries
  • Array methods
• Objects
  • Reading and writing entries
  • Dot vs. Bracket access
  • Object.keys, .values, .entries
• Functions
  • The callstack
  • Recursion

• Sharing arrays and objects between handler functions by reference

• Don't rush, understand! Programming is hard.
  • The examples and exercises will still be there to study later.
  • It's better to fail tests slowly and learn from your mistakes than to pass tests quickly and not understand why.
• Practice Pair Programming: two people, one computer.
• Don't skip the examples! Understanding and experimenting with working code is a very effective way to learn programming.
• Take a look through the Learning From Code guide for more study tips

Projects in this module will be simple websites with onclick attributes that call a handler function.

• User interactions will be handled with prompt, confirm and alert
• Handler functions will use arrays and objects stored in script variables
• There will be tests
