I have this result in javascript and i want to get data that has value more that 3 and i want to put in other array .
"availableDates": {
"2020-01-24": 1,
"2020-01-23": 3,
"2020-01-22": 2,
"2020-01-21": 1,
"2020-01-25": 4,
"2021-01-07": 1
}
I group here :
const formattedDate = x.reduce((acc,el) => {
const date = el.split(" ")[0];
acc[date] = (acc[date] || 0) + 1;
return acc;
}, {});
now I want to put in other array all that date that has value more than 3 . For example
newarray = [ "2020-01-23", "2020-01-25" ]
Why don't use a simple .filter()
over keys of "availableDates"
:
const grouped = { "availableDates": { "2020-01-24": 1, "2020-01-23": 3, "2020-01-22": 2, "2020-01-21": 1, "2020-01-25": 4, "2021-01-07": 1 } }; const newArray = Object.keys(grouped.availableDates).filter((key) => grouped.availableDates[key] >= 3); console.log(newArray);
You can simply use a for...in
loop to iterate over object keys and filter them:
const data = { "2020-01-24": 1, "2020-01-23": 3, "2020-01-22": 2, "2020-01-21": 1, "2020-01-25": 4, "2021-01-07": 1 }; const reducer = (obj, val) => { const result = []; for(key in obj) { if(obj[key] >= val) result.push(key); }; return result; }; console.log(reducer(data, 3));
You could have something like this. I write a complete bunch of the code to make you able to copy/past to test
var availableDates = new Array()
var availableDates = {
"2020-01-24": 1,
"2020-01-23": 3,
"2020-01-22": 2,
"2020-01-21": 1,
"2020-01-25": 4,
"2021-01-07": 1
}
var results = new Array();
for (date in availableDates){
if (availableDates[date] >= 3){
results.push(date)
}
}
console.log(results)
