Debugging

Day28: 18 August 2020

**Today’s Progress:**

Review common mistakes:

  • Syntax errors
  • Runtime errors
  • Semantic errors

Using console.log and console.clear to verify proper code operation.


Use the typeof operator to find out the type of a variable. There are six in total, plus a special one:

  1. Boolean
  2. Null
  3. Undefined
  4. Number
  5. String
  6. Symbol (ES6)
  7. *Object*

OBOE: Off-by-one errors


"Falsy" value:

  • false
  • 0
  • "" (empty string)
  • NaN
  • undefined
  • null
Passed 12/12

**Thoughts:**

I am making progress thanks to freeCodeCamp which will help me for the fifth OpenClassRooms project!

Everything outside the comfort zone is progress!
