Is there a way to create a Map in TypeScript where each member contains an array of strings, all in a single statement?
I attempted the following:
private gridOptions: Map<string, Array<string>> = {"1": ["test"]};
However, I encountered this error:
Module build failed: Error: /Users/*****/Work/dashboard/src/app/core/pg.service.ts (8,5): Type '{ "1": string[]; }' is not assignable to type 'Map<string, string[]>'.
According to the documentation from Mozilla regarding Maps, initialization can be done as shown below:
private _gridOptions:Map<string, Array<string>> =
new Map([
["1", ["test"]],
["2", ["test2"]]
]);
dataStructure: Map<string, string[]> = new Map();
To add data to the Map:
dataStructure.set("x", ["y", "z"]);
To access elements from the map:
dataStructure.get(key);// "x" in this example
Alternatively, you can also do it like this
dataStructure: Map<string, string[]> = new Map([['x', ['y', 'z']]]);
