Coding problem5
I scheduled the interview in the afternoon. The interviewer was okay.
1. Javascript Equality Checks
console.log(Number('name')===Number('name'));
console.log(NaN === NaN);
console.log(undefined === undefined);
console.log(null === null);
Problem approach
If you know about how JS work internally, you can easily solve. I solved 2 question but others I predicted wrong.
2. Javascript Reduce
Explain about Reduce method. Also write the polyfill of reduce method. (Learn)
3. Javascript Prototypes
What is prototype and prototype chaining? Follow up - Where this prototype chaining ends? (Learn)
Problem approach
I explain properly but was unable to tell where it will end in DOM.
4. Javascript Closures
Write a closure example and explain its real life use cases in React.js. (Learn)
5. Code Output
function Outer() {
this.count = 1;
return function () {
this.count++;
console.log(this.count);
};
}
const obj = new Outer();
const fn = obj();
fn();
