Programming Fundamentals in TypeScript

Explore the number type in TypeScript, including integers and decimals, binary representation basics, arithmetic operations, maximum values, and big integers.

Learn how numbers limit precision beyond the maximum safe value, why big integers are needed, and how comparisons work between number and BigInt while arithmetic between them isn't supported.

Explore a TypeScript bank profit calculator that models monthly, quarterly, semi-annual, and annual profits, computes profits from a given balance, and outputs results with console logs.

Explore how if else conditions in TypeScript check conditions to choose true or false paths and control flow through comparisons and simple variable examples.

Learn how the while loop repeats a task based on a condition rather than a fixed count, contrasting it with a for loop using simple input and termination examples.

Refactor the bank profit calculator in the TypeScript course by consolidating profit rate logic into a single property and enabling monthly, quarterly, semi-annually, and yearly calculations via a loop.

Master the basics of conditions and value switch statements in TypeScript, reinforce learning with practical examples, and preview upcoming modules in this programming fundamentals course.

Learn advanced types in TypeScript, including any, undefined, void, and never, plus type alias, type guard, and union and intersection types, with a module project.

Explore type alias in TypeScript, which gives a new name to an existing type without creating a new type. Use aliases for numbers, strings, and data like objects and interfaces.

Learn how union types in TypeScript let a variable hold multiple data types (number, string, boolean) and how intersection types require all types together, often producing never for incompatible primitives.

Learn anonymous functions in TypeScript by assigning unnamed functions to variables, passing them as arguments, and invoking them to perform operations like addition with console output.

Explore arrow functions in TypeScript, transforming traditional function syntax into concise one-liners that omit brackets and the return keyword while preserving the same behavior and arguments.

Explore the four parameter types in functions, including required, optional, and default parameters, and examine them one by one.

Explore required parameters in TypeScript by examining a barometer function that demands multiple arguments. Learn how omitting a required parameter triggers an error, reinforcing proper function calls.

Explore optional parameters in TypeScript by using a question mark. Check for undefined to return the first value, and use a second value when provided.

Explore rest parameters in TypeScript by collecting a varying number of arguments into a single rest array and processing them as a string or other types.

Convert a bank profit calculator to a functional TypeScript approach by defining a bank profit function with typed parameters, then reuse it for multiple accounts.

Explore a complex TypeScript geometrical drawings example using anonymous and named functions to draw circle, square, rectangle, and triangle in a console app, with required, default, and optional parameters.

Explore how programming treats everything as objects with properties, attributes, and methods, and how constructors create objects within classes from blueprints.

Explore access modifiers in classes and objects, distinguishing public, protected, and private properties through a student and chemistry student example, and learn how default public access affects object visibility.

Explore access modifiers in TypeScript by applying public, protected, and private to class methods, controlling visibility inside and outside the class with practical method examples.

Illustrates the static keyword in TypeScript, showing that static properties and methods belong to the class rather than instances, providing a single class-level value accessible via the class.

Learn how generics in TypeScript let you write a single, reusable function that works with strings, numbers, and objects while maintaining type checking.
