  • Q1. Hoisting in javaScript
  • Ans. 

    Hoisting is a behavior in JavaScript where variable and function declarations are moved to the top of their containing scope during compilation.

    • Variable declarations are hoisted to the top of their scope, but not their assignments.

    • Function declarations are fully hoisted, meaning they can be called before they are declared.

    • Hoisting can lead to unexpected behavior if not understood properly.

  • Answered by AI
  • Q2. What are callbacks
  • Ans. 

    Callbacks are functions passed as arguments to another function to be executed later.

    • Callbacks are commonly used in asynchronous programming to handle events or responses.

    • They can be used to perform actions after a certain task is completed.

    • Callbacks can also be used for error handling or to pass data between functions.

Why are women still asked such personal questions in interview?
I recently went for an interview… and honestly, m still trying to process what just happened. Instead of being asked about my skills, experience, or how I could add value to the company… the questions took a totally unexpected turn. The interviewer started asking things like When are you getting married? Are you engaged? And m sure, if I had said I was married, the next question would’ve been How long have you been married? What does my personal life have to do with the job m applying for? This is where I felt the gender discrimination hit hard. These types of questions are so casually thrown at women during interviews but are they ever asked to men? No one asks male candidates if they’re planning a wedding or how old their kids are. So why is it okay to ask women? Can we please stop normalising this kind of behaviour in interviews? Our careers shouldn’t be judged by our relationship status. Period.
