Why is it that my TypeScript isn't permitting the definition of Tuple Types?

When attempting to define a tuple type in my code, an error is being thrown. Is there a specific configuration within my Node.js application that needs to be adjusted in order to accept tuple types?

Answer №1

It appears there are a few syntax errors in your code, but it seems like you are attempting to assign a name to a tuple.

type color = [red: number, green: number, blue: number]

The issue with the error is that the type Spectra cannot be declared in that way. Here are some alternative approaches:

type Spectra = [
  [red: number, green: number, blue: number]
]

// or

interface Spectra {
  color: [red: number, green: number, blue: number]
}
