React hooks are functions that let you use state and other React features without writing a class.
Hooks allow functional components to manage state and lifecycle events.
Common hooks include useState for state management and useEffect for side effects.
Example of useState: const [count, setCount] = useState(0);
Example of useEffect: useEffect(() => { document.title = `Count: ${count}`; }, [count]);
Custom hooks can...
A closure is a function that retains access to its lexical scope, even when executed outside that scope.
A closure is created when a function is defined inside another function.
It allows the inner function to access variables from the outer function's scope.
Example: function outer() { let x = 10; return function inner() { return x; }; }
Closures are often used for data encapsulation and maintaining state.
They can he...
JavaScript scopes define the accessibility of variables: global, function, and block scopes each have unique rules.
Global Scope: Variables declared outside any function or block are globally accessible throughout the code.
Example: `var globalVar = 'I am global';` can be accessed anywhere in the script.
Function Scope: Variables declared within a function are only accessible inside that function.
Example: `function m...
