I have data that looks like this
let countsRaw= [ 7, 8, 7, 6]
I would like the output to look like this
let countsObj = {
6: {count : 1, filterState : false},
7: {count : 2, filterState : false},
8: {count : 1, filterState : false},
}
I have tried numerous different orientations but am not getting the output I expect from the code below, any explanation or direction would be greatly appreciated.
let countsObj = {};
countsRaw.forEach((x) => ({
count: (countsObj[x] = (countsObj[x] || 0) + 1),
}));
the result is
countObj = {6: 1, 7: 2, 8: 1}
I can't figure out why the nested objects are not being added.
Thanks (:
You just forgot to add the nested object.
const countsRaw = [ 7, 8, 7, 6];
const output = {};
countsRaw.forEach(e => {
if (e in output) {
output[e].count += 1;
}
else output[e] = { count: 1, filterState: false};
});
console.log(output);Heres what I would do:
let duplicatesRemoved = [...new Set(array)].sort();
let countsObj = {};
duplicatesRemoved.forEach((v,i) => {
countsObj[v] = {count: i, filterState: false}
});
