Typescript map.get return undefined

Question

When I want get Object by key I have undefined each all element.

My Map :

nodesMaps : Map<number, Object> = [
{ key: "1", value: Object },
{ key: "2", value: Object },
{ key: "3", value: Object },
]

When I want get value of this map :

this.nodesMaps.get(1) // return undefined
this.nodesMaps.get("1") // return undefined

You've messed many things.

1. Even if you declared type Map, you assigned an Array value.
2. The array was array of objects, not array of arrays with length 2. etc.

Valid map creation should look like this:

let nodesMap = new Map([
    [1, 'foo'],
    [2, 'bar'],
    [3, 'baz'],
])
    
 console.log(nodesMap.get(1)) // foo
