Currently Playing: Javascript interview question | closures in javascript

Hello there, Welcome to comscience simplified. In this week's video, we will look into closures in javascript which is one of the most important javascript interview questions. We are planning to start out with a concept that is a hot favorite of many interviewers i.e. Scopes & Closures. Today, we will take this common interview question with the 'for' loop and a variable in the closure scope to analyse the output of the code snippet. We will look at a work-around solution and then, an efficient, optimized solution to this problem. Here are some links to our other popular videos: 1.
