Explore the basics of JavaScript, including single thread execution and synchronous versus asynchronous tasks, with examples using the V8 engine, browser scripts, and Node.js.
Explore how JavaScript variables store temporary data using var, let, and const. Learn about redeclare, reassign, and scope rules, including global and block scope.
Explore JavaScript data types, including strings, numbers, booleans, undefined, null, symbol, and non-primitive objects and arrays, with indexing and object property examples.
Explore JavaScript operators, including arithmetic, assignment, and comparison; learn string concatenation, increment and decrement, modulus, division, and type checks with NaN.
Explore JavaScript conditions with if else, including if statements, else if, and else blocks with curly braces, using age checks for voting eligibility and invalid input.
Explore the JavaScript ternary operator as a short form of if else in one line of code, with examples showing vote eligibility by age and invalid input handling.
Explore the JavaScript switch statement, its syntax with switch, case, and default, and how to handle invalid input, with a note on when to use a ternary for concise code.
Explore JavaScript strings, including quotes, length, slice, trim, replace, and concat, to manipulate text. Learn to access characters with indexing and charAt, and convert case with toUpperCase and toLowerCase.
Explore JavaScript arrays, creating and accessing values by index, and mastering essential array methods like push, pop, shift, unshift, slice, splice, and concat to manipulate and inspect data.
