let map = new Map(); | |
map.set("a", 1); | |
map.set("b", 2); | |
map.set("c", 3); | |
let obj = Array.from(map).reduce((obj, [key, value]) => ( | |
Object.assign(obj, { [key]: value }) // Be careful! Maps can have non-String keys; object literals can't. | |
), {}); | |
console.log(obj); // => { a: 1, b: 2, c: 3 } |
If a value in the map can be an array of maps you need:
const toObject = (map = new Map) => {
if (!(map instanceof Map)) return map
return Object.fromEntries(Array.from(map.entries(), ([k, v]) => {
if (v instanceof Array) {
return [k, v.map(toObject)]
} else if (v instanceof Map) {
return [k, toObject(v)]
} else {
return [k, v]
}
}))
}
