Get different object property value in each access | JavaScript Interview Question - 49

JavaScript Interview Question - 49 | In this video, we will see how to solve a medium-difficulty problem asked in frontend engineer interview to SDE1, SDE2, and SDE3.

We have to implement a solution in which we get different property values of an object every time it is accessed. This question was asked in Rippiling's interview for SDE2+.

Loved the question? I have 120+ such solved problems in my ebook "JavaScript Interview Guide". If you are preparing for Interviews and looking for a solutions book, Get my Ebook.

Hi Prashant, solved it on my own.

//Below is my code
let obj = {
a: 0
}

const handler = {
get: (target, prop) => {
if(prop === 'a'){
target[prop] += 1
}
return target[prop]
}
}

obj = new Proxy(obj, handler)

console.log(obj.a)
console.log(obj.a)

obj.a = 10
console.log(obj.a)
console.log(obj.a)
console.log(obj.a)

Its better to use debugger when an object is modifying just after definition instead of relying on console.
