Explore function declarations in TypeScript, compare with JavaScript, define typed return values, generics, void, and string arrays, and learn to compile with tsc and run with node.

Explore arrow functions in TypeScript, learn how const variables are used with simple numbers, and examine their role in console logging and sorting within body cam logic.

Explore optional parameters in TypeScript functions, learn when to pass a value or mark as optional, and use string interpolation to return typed data.

Understand default parameters and optional parameters in TypeScript, see how a default value is used when a parameter is not provided, demonstrated with a multiply function.

Discover how to create classes in TypeScript, define constructors and properties, and instantiate objects with the new operator, including a name string property and basic methods.

Explore TypeScript constructors and properties, initializing objects with parameters like name and gender, handling optional parameters, and applying access modifiers to control property access.

Explore access modifiers in object oriented data hiding, including private, public, and protected, and their use inside and outside the class with inheritance.

Explore the difference between abstract classes and interfaces, focusing on abstract and implemented methods, method signatures, and how access modifiers apply to properties and members.

Learn how to configure TypeScript with tsconfig.json, initialize settings, manage modules and emit, and enable experimental decorators for controlling target JavaScript output.

Explore decorators in TypeScript, applying class, property, and method decorators to modify behavior, log messages, and configure tests through practical examples and configuration experiments.

Explore how TypeScript enums organize related constants, including numeric and string enums, default values, and practical examples like directions and colors to improve code readability.

Explore mixins as a reusable approach in TypeScript to extend components without strict inheritance, using generic types, decorators, and constructors, and manage active states and timestamps.

Explore type guards and union types in TypeScript by analyzing interfaces and classes that implement behavior like fly or swim, with practical type-safe checks.

Organize code with modules in TypeScript by separating logic into files, exporting and importing functions, and using parameters, data types, and string interpolation, then run and log results with Node.

Learn how namespaces prevent naming conflicts in TypeScript by organizing modules, exporting shapes like circle, and using area calculations with radius and pi.

Create and use promises in TypeScript to manage asynchronous tasks with resolve and reject, and explore async/await usage, then chain with then and catch for API calls and set timeout.

Master promise chaining in TypeScript by sequencing tasks with resolve and reject, using setTimeout and then to manage sequential results and a final console print.

Master async/await and promises through error handling, chaining, and data fetching, including return data types, set timeouts, and basic debugging with console logs.

Create and organize TypeScript files, configure tsconfig and webpack, set up src and public folders, and run the app with npm start to generate browser-ready JavaScript.

Explore import and export in TypeScript, compile ts files to JavaScript with tsc and bundlers, and troubleshoot issues like export not defined during npm start.

Learn to configure Webpack to compile TypeScript into JavaScript, set entry points and output, choose a Webpack CLI or TS loader, and build a bundled app.js with npm run build.

Implement a basic UI for a contact manager using TypeScript and CSS, wiring text and email inputs with labels and a submit button, while refining font family, margins, and padding.

Explore implementing a generate unique id function in TypeScript, exporting a function to create a unique key from dates, randomness, and base 36 conversions, with string data handling.

Learn how to add a contact in a TypeScript context by generating a unique id, importing and exporting functions, and creating a new contact object within a UI-driven workflow.

Explore how to build an add contact form in a web ui, using document.getElementById, html form element, and input values for name and email, with a submit listener.

Enhance the ABM contact application by updating render logic for edit and delete actions and wiring edit and delete buttons to modify contacts in place.

Implement delete contact functionality in a TypeScript app by wiring a delete function to UI actions, filtering by contact id, and handling callbacks to remove the contact and related data.

Implement an edit contact feature by locating a contact using its ID from a context array, populating name and email inputs, and updating or saving changes via the edit button.

Learn how to use local storage to store and retrieve data, stringify and parse JSON, handle null and default, and read content via export function for a UI.

Learn how a user interface uses local storage to save, read, update, and delete data, refresh the browser, and manage a store with render and context.

Set up a React project with TypeScript by downloading a template, creating a contact manager app, and organizing components in Visual Studio Code using tsx files.

Create and export a contact class in TypeScript, with a constructor and public id, name, and email as strings. Organize imports using folder or file defaults, with index.tsx behavior.

Explore building a contact list component in TypeScript within a React setup, using props interfaces, a functional component, and mapping over contact data to display names and emails.

Learn to add a contact UI by building a functional component with a contact form featuring name and email inputs, labels, and a submit button.

Learn to manage contact state with the useState hook, handle input changes for name and email, and implement submit logic to add a contact via a parent component.

learn to call a component in tsx app, manage state with use effect and context, fetch data, and store in local storage while building a contact form and API interface.

Learn to run an application by configuring the class name as text, using a text box or region input, and leveraging a React.js template with TypeScript.

Set up a TypeScript project by initializing npm, installing TypeScript and types, configuring tsconfig, and defining the dist output directory in VS Code.

Export a TypeScript user model class with public properties ID, name, email, and password, and implement a constructor to initialize them.

Explore building a user store with a singleton TypeScript service, implementing CRUD operations—create, read by email or id, update, and delete—on a reusable user model and data store.

Implement an Express auth signup route that validates name, email, and password, checks for existing users by email, creates a new user, and returns a success or error response.

Explore the auth route login workflow in TypeScript, validating email and password, handling requests and responses, returning 400 or 401 errors, and signaling login success.

Demonstrate setting up user routes for get all users and get by id, wiring a user store object with a router and exporting the router.
