Refreshed my understanding of JavaScript . I revisited important ideas like different data types, variables, functions, loops, and objects. Also went over newer features in JavaScript, such as arrow functions, template literals, and spread/rest operators. Intentionally left out asynchronous programming, planning to do with react.

Additionally, I revisited topics related to manipulating website elements, handling events and CSS Flex box and absolute positioning, and used it for adding dark mode button to the website.
