Modern JS
A guide to help you learn Modern JavaScript
- The beginning
- The concepts
- JavaScript key concepts & syntax
- Running JavaScript
- The
var&functionkeywords, scope, hoisting andundefined - First class functions: Function declarations, function expressions, hoisting &
undefined - Working with text:
'and"; plus template literals with backticks`and${} - Equality symbols
==,!=,===and!== - Debugging, documenting & logging JavaScript
- Validating and error handling in JavaScript
- Namespaces and block scoping, the problem
- Immediately-invoked function expressions (IIFE): Namespaces and block scoping solved, the early years
- Object assignments and object notation: Namespaces solved another way, the early years
- Lexical scope and the
thisexecution context - Closures: Functions that remember their lexical scope
- The
letandconstkeywords: Block scoping solved, the modern years; plus saner access, defaults & temporal dead zones (TDZ) for variables - The
export&importkeywords and modules: Namespaces solved, the modern years - Pre-ES6 (ES2015) modules detour: CommonJS, AMD and UMD
- Arrow functions with
=> - The
voidkeyword - Function parameter default values
- Generators: Functions with
*and theyieldkeyword - The spread/rest
...operator - The exponentiation operator
** - Asynchronous functions with
asyncandawait - Numeric separators with the underscore
_character
- JavaScript key concepts & syntax

- Primitive data types
- The
stringprimitive data type andStringobject data type - The
numberprimitive data type,Numberobject data type and their limits - The
booleanprimitive data type andBooleanobject data type - The
symbolprimitive data type andSymbolobject data type - The
bigintprimitive data type andBigIntobject data type - The

MapandWeakMapdata types - The
SetandWeakSetdata types - The
ProxyandReflectdata types
- JavaScript object-orientated and prototype-based programming
- Prototype-based programming and the
prototypeproperty - Prototype-based programming and the prototype chain
- Prototype-based programming constructors & static properties, the early years
- Prototype-based programming constructors and inheritance, the early years
- To
newor not tonew - Prototype-based getters and setters with
getandsetkeywords & property descriptors - JavaScript OOP keywords:
class,constructor,extends,super,get,setandstatic, the modern years
- Prototype-based programming and the
- JavaScript for loops
- The
forstatement: Explicit counters, iterations and step sizes, the early years - The
breakandcontinuestatements: Exiting for loops and iterations prematurely - Label statements in
forloops: GoTo a specific point in the workflow - The
whileanddo whilestatements: Loops that run with one expression - The
for instatement: A loop for key-value data structures, the early years
