I am trying to move everything in the Array Results outside and into the original object
this is the object and the array Results can have multiple values
{
"Name": "John",
"Results": [
{
"Type": "DB",
"Immediate_Action": "No",
},
{
"Type": "system",
"Immediate_Action": "Yes",
}
]
}
It should look like this
{
"Name": "John",
"Type": ["DB","system"]
"Immediate_Action": ["No","Yes"]
}
What I have so far is this data will be populated not at once but will be looped until the entire object is completed. mapped[key] is probably wrong.
const mapOscarResults = ({ data }) => {
return data.map(entry => {
let mapped = {...entry};
entry.Results.forEach(key => {
let Type = mapped[key.Type]
if (mapped[key]) {
mapped[key].push(entry.Results[key]);
} else {
mapped[key] = [entry.Results[key]];
}
});
return mapped;
});
};
It's a good case for reduce. Just collect the values for Results keys in arrays...
const input = {
"Name": "John",
"Results": [{
"Type": "DB",
"Immediate_Action": "No",
},
{
"Type": "system",
"Immediate_Action": "Yes",
}
]
}
let output = { Name: input.Name }
output.Results = input.Results.reduce((acc, el) => {
let keys = Object.keys(el);
keys.forEach(key => {
if (!acc[key]) acc[key] = [];
acc[key].push(el[key]);
});
return acc;
}, {});
console.log(output)This should do the trick
const data = {
"Name": "John",
"Results": [
{
"Type": "DB",
"Immediate_Action": "No",
},
{
"Type": "system",
"Immediate_Action": "Yes",
}
]
};
const transformData = data => {
const newData = { Name: data.Name };
newData.Type = [];
newData.Immediate_Action = [];
data.Results.forEach(({ Type, Immediate_Action }) => {
newData.Type.push(Type);
newData.Immediate_Action.push(Immediate_Action);
});
return newData;
}
const newData = transformData(data);
console.log(newData);
const data = {
"Name": "John",
"Results": [{
"Type": "DB",
"Immediate_Action": "No",
},
{
"Type": "system",
"Immediate_Action": "Yes",
}
]
};
const restructure = obj => {
obj.Results = obj.Results.reduce((accumu, current) => {
for (const [key, val] of Object.entries(current)) {
accumu[key] = [...accumu[key] ?? '', val] ;
}
return accumu;
}, {});
return obj;
}
console.log(restructure(data));
