I understand how to specify the type for a variable.
let members: string[] = [] // this example works flawlessly
My goal is to have an array of strings within an object. How can I structure it correctly?
const team = {
name: String,
members<string[]>: [], // encountering an error with this code!!
}
The resolution
const team = {
name: String,
members: [] as string[]
}
To define the object type, you can explicitly declare the type of the entire object by specifying it after a colon before the assignment operator =. For example:
const team: {
name: StringConstructor;
members: string[];
} = {
name: String,
members: [],
};
Alternatively, you can assert the type of individual properties using as, but this method is not preferred as it should be reserved for cases where there is no other way to annotate the type:
const team = {
name: String,
members: [] as string[],
};
