Actual Output :
[["Name","Age","Location","Gender"],["Mary",28,"KY","F"],["Jonathan",34,"NJ","M"],["Kevin",31,"CA","M"]]
Expected output :
[
{
"Name":"Mary",
"Age":28,
"Location":"KY" ,
"Gender":"F"
},
{
"Name":"Jonathan",
"Age":34,
"Location":"NJ",
"Gender":"M"
},
{
"Name":"Kevin",
"Age":31,
"Location":"CA",
"Gender":"M"
}
]
Please help me with this. So that I can iterate in table.
Thanks in advance
Try this:
const input = [["Name", "Age", "Location", "Gender"], ["Mary", 28, "KY", "F"], ["Jonathan", 34, "NJ", "M"], ["Kevin", 31, "CA", "M"]];
const keys = input[0];
const output = input.slice(1).map(entry => {
const retVal = {};
keys.forEach((key, index) => {
retVal[key] = entry[index];
});
return retVal;
});
console.log(output);Destructure the keys from the values. Map the array of values (vals), and use Object.fromEntries() to create an object by mapping each values sub-array (varr), and combining with the respective key to create an array of [key, value] entries.
to create an object from the values and the keys:
const objecttify = ([keys, ...vals]) => // destructure the keys and an array of values
vals.map(varr => // map the values
Object.fromEntries( // convert the entries to an object
varr.map((v, i) => [keys[i], v]) // create the entries by combining a value with it's respective key
)
)
const arr = [["Name","Age","Location","Gender"],["Mary",28,"KY","F"],["Jonathan",34,"NJ","M"],["Kevin",31,"CA","M"]]
const result = objecttify(arr)
console.log(result)
