I have a Map and I want to convert it to an Object filtering out entries that don’t meet some condition.
My first solution was:
let m = new Map([
["key1", { flag: true}],
["key2", { flag: false}]
])
o = Object.fromEntries(m.entries()
.filter(([k,v]) => v.flag)
.map(([k,v]) => [k, true]));
console.log(o)However it appears that iterator.filter is not generally available. So I came up with this alternative:
let m = new Map([
["key1", { flag: true}],
["key2", { flag: false}]
])
let o = Object.fromEntries(
Array.from(m.entries())
.map(([k,v]) => [k, v.flag])
.filter(v => v[1]));
console.log(o)Which I think is better supported.
Is there a better / faster solution? If iterator.filter was widely supported, would the first solution a good solution?
Thanks
