The type 'string' cannot be assigned to the type 'online' or 'offline'. I must be overlooking something, but I'm not sure what it is.
enum StatusOptions {
ONLINE = 'ONLINE',
OFFLINE = 'OFFLINE',
}
Object.keys(StatusOptions).map((item: keyof typeof StatusOptions) => {
return {
text: StatusOptions[key],
value: item
}
})
When you encounter the error "Type 'string' cannot be assigned to type 'online' | 'offline'", it is likely due to a misstyped function parameter being passed into your map function.The definition of <code>Object.keys /**
* Returns the names of the enumerable string properties and methods of an object.
* @param o Object that contains the properties and methods. This can be an object that you created or an existing Document Object Model (DOM) object.
*/
keys(o: object): string[];
To resolve this issue, ensure that your function is correctly typed. In this case, where item should be a string, the correct approach would be:
Object.keys(StatusOptions).map((item: string) => /* do something with it */);
If you want to use the item as a key for StatusOptions like: StatusOptions[item], you need to cast it in the following manner:
Object.keys(StatusOptions).map((item: string) => {
return {
text: StatusOptions[item as keyof typeof StatusOptions],
value: item
}
})
