JavaScript Basics and Core Concepts – Learn in Under 2 Hours

Learn how to declare variables with var, let, and const, understand block scope, and explore JavaScript primitive types and data types like strings, numbers, booleans, null, and undefined.

Master JavaScript operators and expressions by exploring arithmetic, comparison, logical, and assignment operators, and learn operator precedence to perform calculations and control program decisions.

Explore JavaScript control flow with if, else if, else, switch, and the ternary operator to write dynamic conditions applied to voting eligibility, grading, and tickets.

Explore loops in JavaScript, control with for, while, and do-while, and use break and continue to solve real-world problems, including summing numbers.

Explore strings in JavaScript, created with single quotes, double quotes, or backticks. Learn to concatenate with plus or template literals and use methods like toUpperCase, toLowerCase, trim, and length.

Learn how JavaScript functions enable reusable code, covering function declarations, parameters, return values, function expressions, and arrow functions, with examples like adding numbers and calculating a rectangle's area.

Master JavaScript objects and arrays, including creating, accessing with dot and bracket notation, updating properties, and using push, pop, shift, unshift, and forEach, map, filter, and reduce.

Learn to anticipate and handle errors in JavaScript using try, catch, finally, and throw to create robust code that gracefully recovers from issues and supports custom errors.

Learn how to parse JSON strings into JavaScript objects and stringify objects back into JSON, access properties, handle arrays, and work with API data using parse and stringify.

Explore asynchronous programming in JavaScript, mastering callbacks, promises, then/catch, and async/await to handle tasks like API data fetching without freezing the program.
