How to Get Enum Length in JavaScript#

If you are working with enums in JavaScript, you might need to determine the length of an enum. Here are a few ways to accomplish this:

Method 1: Object.keys()#

You can use the Object.keys() method to get an array of the keys in the enum object, and then get the length of that array:

const myEnum = {
    key1: 'value1',
    key2: 'value2',
    key3: 'value3'
};

const enumLength = Object.keys(myEnum).length;
console.log(enumLength); // Output: 3

Method 2: Object.values()#

You can use the Object.values() method to get an array of the values in the enum object, and then get the length of that array:

const myEnum = {
    key1: 'value1',
    key2: 'value2',
    key3: 'value3'
};

const enumLength = Object.values(myEnum).length;
console.log(enumLength); // Output: 3

Method 3: for...in loop#

You can use a for...in loop to iterate over the keys in the enum object and count them:

const myEnum = {
    key1: 'value1',
    key2: 'value2',
    key3: 'value3'
};

let enumLength = 0;
for (let key in myEnum) {
    enumLength++;
}

console.log(enumLength); // Output: 3

These are just a few ways to get the length of an enum in JavaScript. Choose the method that works best for your specific use case!
