Understand what errors tell you

Error messages contain valuable information:

TypeError: Cannot read property 'x' of undefined
    at processUser (app.js:25:10)
    at main (app.js:10:3)

This tells you:

Error type: TypeError
What happened: Accessing 'x' on undefined
Where: app.js line $25$ , column $10$
Call path: main called processUser
