]You can use Array.prototype.reduce() like this:
const data = [
{
name: 'shanu',
label: 'ak',
value: 1,
},
{
name: 'shanu',
label: 'pk',
value: 2,
},
{
name: 'bhanu',
label: 'tk',
value: 3,
},
];
const output = data.reduce((prev, curr) => {
const tmp = prev.find((e) => e.name === curr.name)
if (tmp) {
tmp.label.push(curr.label)
tmp.value.push(curr.value)
} else {
prev.push({
name: curr.name,
label: [curr.label],
value: [curr.value],
})
}
return prev
}, [])
console.log(output)
