Explore conditional statements, including if-else and switch case, and apply strict equality with boolean logic. Learn syntax, nested conditions, else if chains, and the six falsy values.

Explore use case two of the if not condition to catch falsy data and throw errors for no valid data, with examples using undefined, null, zero, and empty strings.

Master if-else scripting by illustrating two outcomes: read a file if it exists, or create it if it does not, using a log file example.

Explore use case five of if-else with inner conditions in database queries, differentiating data, no data, and errors, and using nested ifs to decide continue or fail.

Explore using an if condition inside a for loop in TypeScript to break when i equals 6, printing values up to 5.

Explore switch case syntax, including break and default, and compare it with if-else to handle predefined values or inputs like browser drivers or weekdays.

Explore how JavaScript loops iterate over collections to find elements or operate on them, using for, for each, while, do-while, for-in, and for-of with arrays and objects.

Iterate a mixed array with a standard for loop to sum numbers, using type checks and array length. Demonstrate continue and break as control flow for non-number elements.

Learn how the while loop repeats actions until a condition is true, using an initial value, condition, and increment, with API retry scenarios and maximum retries.

Learn how to compare strings in automation using full and partial matches, including includes, starts with, and ends with, with case sensitivity control, trimming, and boolean outcomes.

Learn how to extract substrings from a string using the slice method in JavaScript, including start and end indices, optional parameters, and negative indexing to obtain year, month, and date.

Learn how backslashes act as escape characters in string literals, and how the interpreter processes the next character to produce quotes, backslashes, or special sequences such as tab and newline.

Explore how functions drive tasks and calculations in JavaScript, including definitions, calls, named versus anonymous forms, and parameters versus arguments. Learn how TypeScript adds type declarations and checks.

This lecture demonstrates named functions in JavaScript and TypeScript, including a value-returning add function and a non-returning click action, with parameters versus arguments and basic type handling.

Explore anonymous functions and function expressions, compare them with named function declarations, and see how callbacks use unnamed functions, including assigning them to variables and managing scope.

Explains function parameters, arguments, and defaults, showing how to use default values, optional parameters, and undefined or falsy values. Demonstrates passing primitives, objects, arrays, and functions as parameters with examples.

Learn rest parameters and the arguments object to sum any number of inputs in a function using three dots, length, and index access.

Master self-invoking function syntax by wrapping the function in parentheses, then supplying arguments to execute it immediately for quick unit testing.

Explore arrow functions, a shorter form of function expressions used mainly in callbacks, with syntax showing left side, arrow, and right side, plus rules about this and parameters.

Install the core Playwright component, initialize a TypeScript project, review the root readme.md, folder structure, and config for Chrome, Firefox, and WebKit.

Run the generated end-to-end tests with Playwright in TypeScript by executing npx playwright test, exploring the auto-created spec files within the test directory across Chromium, Firefox, and WebKit.

Create a target folder structure for the mcp server and playwright setup, including config, data and constants, logs, resources, and test folders (api, devices, end-to-end, functional) following the naming convention.

Install Git on a Windows machine using the standalone installer with the default option, then verify installation by running Git --version in the command prompt to confirm the latest version.

Initialize a local git repository, create master branch, check changes with git status, then git add . and git commit, using .gitignore to exclude dot env before pushing to remote.

Create your first playwright spec file (my test.spec.ts) using test and expect, launch the target URL, and assert the page title and header text with a locator.

Learn to resolve common Playwright errors in first tests by correcting test file names, extending navigation timeouts, and always awaiting action commands.

Add a script to the package.json scripts object and run npm run demo to execute the npx playwright test quickly. Leverage CI CD mode by running commands with npm run.

Explain page fixtures in Playwright, apply the dry principle to avoid repetition, and use the page fixture with locators and get by role, text, or label to navigate and interact.

Master how the expect function drives assertions in Playwright by returning matches for any value and preloading type-specific checks like page url and title.

Explain how the await keyword pauses async functions until promises resolve, enabling stepwise test actions—clicks, fills, and expectations—within Playwright test functions and locator methods.
