Welcome to Modern JavaScript course1:55
Essential tools and resources5:06

Core features of JavaScript6:10
Explore the core features of JavaScript, including its multi‑paradigm nature, dynamic and weak typing, and memory management, with a history from livescript to ecma standards and v8.
Lexical structure5:32
Explore the lexical structure of JavaScript, including statements, comments, semicolon usage, and whitespace, with emphasis on case insensitivity and use strict for function scope.
Identifiers and reserved words4:02
Data types and literals8:40
Explore JavaScript data types and literals, from numbers, strings, booleans, objects, null, undefined, symbols, to bigints, including template literals with expressions and number formats like hex, octal, and binary.
Sample code: Examples of different literals0:25

Expressions5:41
Operators, part 16:11
Sample code: Arithmetic operators and string concatenation0:23
Operators, part 26:42
Operators, part 34:42
Explore assignment operators, destructuring, and the spread operator to simplify data handling, with array and object destructuring, defaults, and rest and ellipsis syntax.
Operators, part 44:54
Explore JavaScript operators in depth, including typeof, instanceof, in, delete, void, and the comma operator, with examples of behavior in objects, arrays, and strict mode.
Sample code: Using different operators0:20
Implicit type conversion4:49
Sample code: Type conversion examples0:25

General info about statements2:29
Explore how JavaScript executes statements, including empty, block, and expression statements, and the role of semicolons. Learn about common side-effect expressions like assignments and function calls.
Variable declarations5:05
Sample code: Variable declaration statements0:26
Conditional branching3:38
Loops3:59
Sample code: Branch statements and loops0:21
Unconditional branching2:51
Mastering exception handling4:09
Sample code: Handling and throwing exceptions0:20

Creating arrays5:14
Array indexes and length5:05
Traversing arrays2:37
Sample code: Creating arrays and working with elements0:23
Array methods, part 17:47
Array methods, part 26:23
Explore slicing, sorting, reordering, and converting arrays using methods like slice, splice, fill, copyWithin, indexOf, includes, join, and isArray.
Sample code: Using various array methods0:25
Array-like objects3:11
Explore array-like objects in JavaScript, learn how they resemble arrays but lack direct methods, and discover borrowing array methods via call or apply on objects like arguments and strings.

Global object and its elements5:35
Numbers5:31
Date and time2:52
Sample code: Working with Number and Date0:23
String object7:57
Master the string object in JavaScript, covering immutability, length, indexing, and a comprehensive set of methods for case, trim, replace, normalize, extract, and search, plus template literals and tagged templates.
Regular expressions3:38
Sample code: Strings and regular expressions0:21
The symbol type3:41

Creating objects9:38
Working with properties7:06
Sample code: Creating objects and using their properties0:25
Understanding property metadata6:33
Learn property metadata in JavaScript, including writable, enumerable, configurable, and value, plus get and set. Explore defining property descriptors and using get own property descriptor and Object.create.
Exploring object metadata3:56
Sample code: Property metadata and object metadata0:24

Understanding prototypes8:09
Explore how prototypes drive prototypal inheritance in JavaScript, including the prototype chain, reading vs writing properties, and setting prototypes with Object.create, new, or setPrototypeOf.
Sample code: Working with prototypes0:22
Constructor functions4:27
Explore constructor functions as a core object oriented pattern in JavaScript, using the new operator and prototypes to create multiple objects with shared methods and encapsulated private fields.
Sample code: Modelling some aspects of OOP0:21
Classes5:58
Class inheritance3:05
Explore how class inheritance works in JavaScript using extends and super, showing code reuse, an employee from person example, and color point extending point.
Sample code: Examples of classes0:22

Requirements

No prior knowledge of JavaScript is required. Basic familiarity with programming concepts (like variables and conditions) is helpful but not mandatory. All tools used are free and instructions will be provided.

Description

Modern JavaScript is a comprehensive course that takes you deep into the core of the JavaScript language — from the very basics to advanced concepts. Whether you're new to JavaScript or want to fill in knowledge gaps, this course is designed to help you understand how the language really works.

We’ll cover the full range of topics, including ES2024 syntax, types and expressions, functions and closures, arrays, objects, prototypes, classes, asynchronous programming with promises and async/await, and much more.
