Code: Intrucstion
Expressions are questions that Javascript can answer. Javascript answers expressions in the only way it knows how - with values.
Variables are Wires, Varaibles are not Values
Values:
  Types of Values:
    Primitive Values: Immutable values
      1. Undefined
        One value is undefined
      2. Null
        One value is null
      3. Boolean
        Two value is true and false
      4. Number
        -2^64 --> 2^64 values
      5. BigInt
        Infinity values
      6. String
        Infinity values
      7. Symbol

    Object
      {}
    Function
      ()
  Checking a type: typeof 
Equality of Values
  Same is equal: Object.is()
  Strict equal === 
    NaN === NaN : false
    0 === -0: true
  Lose equal ==
 Properties
  Similar variables but variables start from my code, properties start from object.
  obj.property is calculated in three step:
    1. figure out which value in on the left
    2. If it's null or undefined, throw an error
    3. If that property exists, the result in the value it points to. If that property doesn't exist, the result is undefined.
Mutation
  Objects are never "nested" in our universe - pay close attention to the wires
  Carefully
Prototype
  Link object to object
