Value ↔ immutable data saved at Memory Address

Reference Value​

anything !primitive where Value is pass by reference

Primitive Value​

undefined, null, number, bigint, boolean, string, symbol

Value is ref by Identifier

Identifier​

name/reference for Variable as pointer to bind a Value to a memory address

Memory Address​

place in Memory where Value stored

This keeps a Reference to where the object is located in the heap

Basic copying only duplicates the reference to heap address and not the object value itself

References​

  1. Memory Address ↔ place in Memory where Value stored

  2. Variable ↔ named ref (Identifier) bound to a Value

  3. Binding ↔ (formal ECMAScript term for Variable) Identifier to catch & hold Value 🐭

  4. NaN ↔ Number Property to rep Value of Not-a-Number

  5. Referential Equality ↔ Objects equivalent based on Memory Address location NOT Value

  6. @returns ↔ JSDoc tag to set return Value

  7. Parameter Default Value ↔ JS Syntax used to specify default Value for a Parameter if not provided

  8. = ↔ Assignment Operator to bind Value to Identifier & save at Memory Address

  9. Reference Value ↔ anything !primitive where Value is pass by reference

  10. .then() ↔ async Chain Method to execute Callback on Fullfill, auto-pass Promise Value as arg

  11. Expression ↔ single line of Code to evalute to a Value

  12. Identifier ↔ name/reference for Variable as pointer to bind a Value to a memory address

  13. Memory Leak ↔ old Values clogging up Heap; left behind, not removed

  14. Generic Type Variable ↔ special Variable that works on Types instead of Values

  15. Initializer ↔ Value assigned to Enum Member name

  16. Accessor Property ↔ Value Modifier to set access via Getter & Setter Method

  17. function ↔ callable Block of code to perform action or return Value

  18. Boolean Context ↔ whether Value Coerces to Truthy || Falsy

  19. Type Assertion ↔ TS Syntax to override TSC's Type Inference for Static Type of specific Value

  20. Destructuring ↔ JS Syntax shorthand to extract elements from iterable & assign to Value

  21. Argument ↔ Value import as Parameter input to function
