By using the Object.keys() and Object.values()

By using the for-in loop

We can use the Object.keys() method to get the names of each key of the enum and the Object.values() method to get all the values in the form of an array.

Example: The below example will illustrate the use of the above method to get the names of enum entries in the form of an array.

Javascript 
enum Cricketer {
    Sachin,
    Virat,
    Rohit,
    Dhoni,
    Jadeja
}

const namesArray = Object.keys(Cricketer);
console.log(namesArray);

const valuesArray = Object.values(Cricketer);
console.log(valuesArray);

Output:

[0, 1, 2, 3, 4, Sachin, Virat, Rohit, Dhoni, Jadeja] 
[Sachin, Virat, Rohit, Dhoni, Jadeja, 0, 1, 2, 3, 4]
