Having the specific NameUnion type, it is important for consistency that I define it once and later on check if an array contains an element from the NameUnion type.
type NameUnion =
// Home && login
| 'email'
| 'newEmail'
| 'password'
| 'passwordConfirm'
| 'deleteAccountPassword'
if(['email','newEmail','password','passwordConfirm','deleteAccountPassword'].includes(name)){
// do somthing
}In this particular instance, the NameUnion represents the type, while the nameArray embodies an array of that specific type. It serves as a tool for the inclusion check you desire. By employing the doSomething function, you can assess whether a parameter of type NameUnion is present in the nameArray.
This recommended strategy entails the following:
type NameUnion =
| 'email'
| 'newEmail'
| 'password'
| 'passwordConfirm'
| 'deleteAccountPassword';
const nameArray: NameUnion[] = ['email', 'newEmail', 'password', 'passwordConfirm', 'deleteAccountPassword'];
function doSomething(name: NameUnion): void {
if(nameArray.includes(name)){
// Implement actions here
console.log(`name is in the NameUnion: ${name}`);
} else {
console.log(`name is NOT in the NameUnion: ${name}`);
}
}
// Test Cases
doSomething('email'); // Expected output: "name is in the NameUnion: email"
doSomething('other'); // Expected output: "name is NOT in the NameUnion: other"
