I am new to this please excuse me if I make any mistake.
I am reading a single row of data from database , the data which I receive is JSON object and looks like this:
var details = {jan: '2591.00', feb: '4898.00', mar: '26290.00', apr: '22719.00', may: '26528.00',start: '2020', end: '2022', v1: '34', v2: '22'};
Now I want to alter/modify this JSON object so it looks like this:
var details = [
{jan: '2591.00',start: '2020', end: '2022', v1: '34', v2: '22'},
{feb: '4898.00',start: '2020', end: '2022', v1: '34', v2: '22'},
{mar: '26290.00',start: '2020', end: '2022', v1: '34', v2: '22'},
{apr: '22719.00',start: '2020', end: '2022', v1: '34', v2: '22'},
{may: '26528.00',start: '2020', end: '2022', v1: '34', v2: '22'}
]
MY Approach: I have been trying to achieve this by using :
result = Object
.keys(details)
.map(k => ({ [k]: details[k] }));
However, it will break at each key-value pair.
var details = {jan: '2591.00', feb: '4898.00', mar: '26290.00', apr: '22719.00', may: '26528.00',start: '2020', end: '2022', v1: '34', v2: '22'};
var details = [
{jan: '2591.00',start: '2020', end: '2022', v1: '34', v2: '22'},
{feb: '4898.00',start: '2020', end: '2022', v1: '34', v2: '22'},
{mar: '26290.00',start: '2020', end: '2022', v1: '34', v2: '22'},
{apr: '22719.00',start: '2020', end: '2022', v1: '34', v2: '22'},
{may: '26528.00',start: '2020', end: '2022', v1: '34', v2: '22'}
]let details = {
jan: '2591.00',
feb: '4898.00',
mar: '26290.00',
apr: '22719.00',
may: '26528.00',
start: '2020',
end: '2022',
v1: '34',
v2: '22'
};
let months = ['jan', 'feb', 'mar', 'apr', 'may'];
let detailsByMonth = months.map(month => ({
[month]: details[month],
start: details.start,
end: details.end,
v1: details.v1,
v2: details.v2
}));
console.log(detailsByMonth);Here is a one liner. First I filter the keys of the object based on what you don't want inside the array (opposite can be done as well). Then I map them into objects of required type.
const mappedDetails = Object.keys(details)
.filter((i) => !["v1", "v2", "start", "end"].includes(i))
.map((j) => ({
[j]: details[j],
start: details.start,
end: details.end,
v1: details.v1,
v2: details.v2
})
);
try this
var arrContinue = ["start", "end", "v1", "v2"];
const newDetails = Object.keys(details)
.filter(k => (arrContinue.indexOf(k) == -1))
.map(k => ({
[k]: details[k],
start: details.start,
end: details.end,
v1: details.v1,
v2: details.v2,
}));
