How it works
Async Maps work similar to JavaScript Maps and is in fact based on it.
It is a bit more restricive than regular Maps in that it offers no options to check for keys or delete or clear the Map. A value can only be set once for a given key and subsequent uses of the
method would be ineffective.It allows using primitives as keys unlike with WeakMaps.
With Async Maps
getting the value corresponding to a key returns a Promise that resolves to the value when it is set.Usage
`TS
import AsyncMap from '@dnvr/async-maps'const map = new AsyncMap
map.get( 'info' ).then( ( information ) => {
console.log( information )
})
void async function () {
let value = await map.get( 'value' )
console.log( value )
}()
map.set( 'info', 'Hello World!!!' )
map.set( 'value', 1 )
