How to Remove Duplicate from Object Array:

let obj = [{ name: "sangram", age: 60 }, { name: "sangram", age: 60 }, { name: "sagar", age: 56 }, { name: "sagar", age: 56 }]

//method 1

var noduplicates = []

for (let i = 0; i < obj.length; i++) {

let entry = obj[i]

var index = obj.findIndex((t) => {

return t.name == entry.name && t.age == entry.age

})

if (index == i) {

noduplicates.push(entry)

}

}

console.log(noduplicates)

//more refine method

var nodup = obj.filter((entry, index, self) => {

return index == obj.findIndex((t) => {

return t.name == entry.name && t.age == entry.age

})

})

console.log(nodup)
