Debugging with Stack Traces

Read error stack traces

Stack traces show the call path that led to an error. Read from top (where error occurred) to bottom (where execution started).

TypeError: Cannot read property 'x' of undefined
    at processItem (app.js:45)
    at Array.forEach (<anonymous>)
    at processAll (app.js:30)
    at main (app.js:10)

The first line after the error message is usually where to look.
