  • Q2. What is difference between var let and const give me an explanation on what block scope
  • Ans. 

    var, let, and const are used to declare variables in JavaScript. var has function scope, let has block scope, and const is a constant with block scope.

    • var has function scope, meaning it is accessible throughout the function it is declared in.

    • let has block scope, meaning it is only accessible within the block it is declared in.

    • const is similar to let in terms of block scope, but the value cannot be reassigned.

    Asynchronous programming allows tasks to run independently of the main program flow, improving performance and responsiveness.

    • Q1. Alternative way for prop drilling
    • Ans. 

      Context API or Redux can be used as alternative ways for prop drilling in React.

      • Implement Redux to manage global state and access data from any component without prop drilling.

      • Consider using React's useContext hook with Context API for a simpler way to consume context in functional components.
