*Some Useful JavaScript tricks:*
1. *Quick Boolean Conversion*: Use `!!value` to convert any value to true/false instantly.
2. *Default Parameters*: Set default values in functions like `function greet(name = "Guest")` to avoid undefined errors.
3. *Template Literals*: Build dynamic strings easily: `` `Hello, ${name}!` ``.
4. *Destructuring*: Extract values from arrays/objects in one line: `let [x, y] = ;` or `let {name, age} = person;`.
5. *Debounce/Throttle Events*: Prevent performance issues on scroll/resize by debouncing or throttling event handlers.
6. *Replace All in Strings*: Use regex with `/g` flag: `"potato potato".replace(/pot/g, "tom")` gives `"tomato tomato"`.
7. *Memory Management*: Use `AbortController` to clean up event listeners and avoid memory leaks.
