How to use the Object.getOwnPropertyNames() In Typescript

By using the square bracket syntax

Another method to retrieve the names of enum entries is by utilizing the Object.getOwnPropertyNames() function. This method returns an array of all properties (including non-enumerable properties except for those which use Symbol) found directly upon a given object.

Example: In this example the enum entries’ names using Object.getOwnPropertyNames() and filtering out non-enumerable properties, ensuring only enum entries are included in the result.

JavaScript

enum Cricketer {
    Sachin,
    Virat,
    Rahul,
    Dhoni,
    Jadeja
}

const enumEntries = Object.getOwnPropertyNames(Cricketer).filter(
    prop => isNaN(parseInt(prop)));
console.log(enumEntries);

Output:

[ 'Sachin', 'Virat', 'Rahul', 'Dhoni', 'Jadeja' ]
