Semantic tags in HTML are tags that provide meaning and context to the content of a web page, such as <header>, <nav>, <main>, <section>, <article>, <footer>, etc.
position: relative is a CSS property that positions an element relative to its original position, while position: absolute positions an element relative to its parent element or to the body of the page.
The box model in CSS describes how elements are rendered on a web page by defining the size, padding, border, and margin of each element.
The event loop in JavaScript is a mechanism that allows JavaScript to handle asynchronous operations by continuously monitoring the call stack and the task queue.
Promises in JavaScript are used to handle asynchronous operations and provide a way to chain multiple asynchronous operations together. The parameters of a Promise are the resolve and reject functions that are used to determine the outcome of the Promise.
The Document Object Model (DOM) is a programming interface for HTML and XML documents that represents the structure of a web page as a tree-like structure, where each node in the tree represents an HTML element, attribute, or text.
Hoisting in JavaScript is the behavior of moving variable and function declarations to the top of their respective scopes during the compilation phase, so that they are available for use throughout the scope.
A closure in JavaScript is a function that has access to variables in its outer lexical scope, even after the outer function has returned.
Callback hell is a situation in asynchronous programming where the use of multiple nested callbacks makes the code difficult to read, understand, and maintain.
Map, filter, and reduce are higher-order functions in JavaScript that are used to manipulate arrays by applying a function to each element of an array, filtering an array based on a condition, or reducing an array to a single value.
JavaScript has two scopes: global scope and local scope.
call, apply, and bind are methods in JavaScript that are used to set the this value for a function and to pass arguments to a function.
this is a keyword in JavaScript that refers to the object that a function is a method of, or to the global object if the function is not a method of any object.
Arrow functions are anonymous functions in JavaScript that have a shorter syntax than regular functions and do not bind their own this value, while regular functions can have a name and bind their own this value.
Memoization is a technique in JavaScript that caches the results of a function so that if the function is called again with the same inputs, the cached result is returned instead of recomputing the result.
The spread operator (...) in JavaScript is used to expand an iterable (e.g., an array or an object) into individual elements, while the rest operator (...) is used to collect a group of elements into an array.
The virtual DOM in React is a lightweight copy of the actual DOM that is used to update the web page efficiently by minimizing the number of DOM updates needed.
ReactJS is a JavaScript library for building user interfaces that provides a component-based architecture, virtual DOM, and one-way data flow.
One-way databinding is a data binding technique in which data flows in only one direction, from the component to the view, and any changes to the data are not reflected back to the component automatically.
Redux is a state management library for JavaScript applications that provides a predictable state container and a unidirectional data flow.
A higher-order component (HOC) is a function in React that takes a component as its argument and returns a new component with added functionality
Lifecycle methods in React are methods that are called at different stages of a component's life, such as componentDidMount, componentDidUpdate, and componentWillUnmount.
In a functional component in React, lifecycle methods can be handled using the useEffect hook, which takes a function as its argument and is called after the component has rendered. The useEffect hook can be used to handle different lifecycle events by specifying different dependencies.

For each explanation he was saying that's fine.. I would say brilliant..🙃
