To check if a value is in an enum in TypeScript, you can use the `Object.values()` method to get an array of all enum values and then use the `includes()` method to check if the value exists in the array. This is a simple and effective way to determine if a specific value is present in the enum.<\/p>\n

**The key steps to check if value is in enum TypeScript are:**<\/p>\n

1. Get an array of all enum values using `Object.values()`.
\n2. Use the `includes()` method to check if the value is in the array of enum values.<\/p>\n

Here is an example of how you can check if a value is in an enum in TypeScript:<\/p>\n

“`typescript
\nenum Fruit {
\n Apple = ‘apple’,
\n Banana = ‘banana’,
\n Orange = ‘orange’
\n}<\/p>\n

const fruitValue = ‘apple’;
\nconst isFruitValueInEnum = Object.values(Fruit).includes(fruitValue);
\nconsole.log(isFruitValueInEnum); \/\/ Output: true
\n“`<\/p>\n

In this example, we have an enum called `Fruit` with three values. We check if the value `’apple’` is in the enum using the `includes()` method on the array of enum values.<\/p>\n

Using this method, you can easily determine if a specific value is present in an enum in TypeScript.<\/p>\n
