Currently, I am in the process of incorporating the nanostore ReadableAtom interface into my codebase. This interface introduces two distinct properties that may seem unconventional:
export interface ReadableAtom<Value = any> {
...
readonly [actionId]: number | undefined
readonly [lastAction]: string | undefined
I'm curious about the purpose of these bracketed property declarations and how exactly I should go about implementing them to meet the requirements of the interface.
Both actionId and lastAction are predefined as unique symbols.
They would have been defined in the following way
declare const actionId: unique symbol;
declare const lastAction: unique symbol;To implement the interface, you can do it like this
const a: ReadableAtom = {
[actionId]: 12,
[lastAction]: "test"
}In TypeScript, utilizing brackets in property declarations indicates the use of computed property names. This means that the names of the properties are generated dynamically during runtime. Regarding your follow-up inquiry, providing more context or elaborating on how you plan to utilize these computed properties would allow us to offer more targeted assistance.
