To fetch the highest value, use the Math.max() from JavaScript. Since, we want the one with maximum value, use the Object.values.
Example
const studentMarksDetails= { marks1:78, marks2:69, marks3:79, marks4:74 } const maximumMarks = Math.max(...Object.values(studentMarksDetails)); console.log("The highest marks="+maximumMarks); for (const key of Object.keys(studentMarksDetails)){ if (studentMarksDetails[key] == maximumMarks) { console.log(`The Object='${key}'`); break; } }
To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo91.js.
Output
This will produce the following output −
PS C:\Users\Amit\JavaScript-code> node demo91.js The highest marks=79 The Object='marks3'
