Few questions that I could recall are as follows:- const word = ‘hello’ word[1] = ‘m’ console.log(word) console.log(a) const a = 1; There were follow up questions based on var & let Currying and hoisting in javascript Difference between Typescript & Javascript Explain the entire process (what actually happens in backend) starting from sending request from client to server and then back to client.
