Class 10 Readings

Debugging JavaScript

Debugging Principles

  • Consider Order of Operations to pinpoint problems

  • Recognize/identify scope of problems (may mean some vars/functions are isolated)

Hoisting

  • Hoisting: Functions may be called prior to declaration, as with variable assignments (in some cases)

Error Objects

  • Console messages refer to specific information about errors, like specific files/lines, or error types such as syntax and type (see Duckett on JS p459)
