Map type

The Map.<k,v> type represents a hash map.

Note: Property access on a Map equals data access. Method call on a Map equals a Map method use.

Instance usage

const map = new Map.<string,double>();

map.x = 10;
map.y    // ReferenceError.
         //   use "in" before

const fns = new Map.<string,Function>();

fns.m = function() 10;
(fns.m)()       // 10
