Find n highest values in an object JavaScript

Let’s say, we have an object that describes various qualities of a football player like this −

const qualities = {    defence: 82,    attack: 92,    heading: 91,    pace: 96,    dribbling: 88,    tenacity: 97,    vision: 91,    passing: 95,    shooting: 90 };

We wish to write a function that takes in such object and a number n (n <= no. of keys in object) and returns an object with n highest key value pairs.

Like for n = 2

Output should be −

{    tenacity: 97,    pace: 96 }

Therefore, let’s write the code for this function,

The complete code for this function will be −

Example

const qualities = {    defence: 82,    attack: 92,    heading: 91,    pace: 96,    dribbling: 88,    tenacity: 97,    vision: 91,    passing: 95,    shooting: 90 }; const pickHighest = (obj, num = 1) => {    const requiredObj = {};    if(num > Object.keys(obj).length){       return false;    };    Object.keys(obj).sort((a, b) => obj[b] - obj[a]).forEach((key, ind) =>    {       if(ind < num){          requiredObj[key] = obj[key];       }    });    return requiredObj; }; console.log(pickHighest(qualities, 3));

Output

The output in the console will be −

{ tenacity: 97, pace: 96, passing: 95 } { tenacity: 97 } { tenacity: 97, pace: 96, passing: 95, attack: 92, heading: 91 }
