Get a specific key in a javascript object fast

Question

Currently this is my code for getting the key that I want from my Object:

for (let [key, value] of Object.entries(d)) {
   if (key == input){
      //do something
   }
}

Is there a faster way to get that key without iterating through every entry? Thank you

Answer 1

Find will find and return first element founded, so theoretically if you element lays first it will be blazing fast

Object.keys(obj).find(key => obj[key] === value)

Answer 2

You're probably looking for:

d[input]
