how to remove duplicate objects from an array in reactjs

Question

I want to remove the duplicate objects in the array which was rendered on state change.

Below i have given the console output which has got 14 objects out of which 7 are duplicate.

I have used reduce, but the id which has got a different jobid also get deleted... I must filter based on jobid and remove the duplicate object which has got the same id.

appliedCandidate: Array(14)
0: {jobid: "atA3Qi4BJu01VrUasiSX", id: "I1bncvyBsjbu7ePdPvYt", firstName: "Krishnakumar K R", Title: "design job", empname: "Rakesh", …}
1: {jobid: "atA3Qi4BJu01VrUasiSX", id: "MDxEVS2hKftDrrPXsSWL", firstName: "test Candidate", Title: "design job", empname: "Rakesh", …}
2: {jobid: "atA3Qi4BJu01VrUasiSX", id: "Mmu7oiAoCNcaU2ZWlLeS", firstName: "Rakesh", Title: "design job", empname: "Rakesh", …}
3: {jobid: "atA3Qi4BJu01VrUasiSX", id: "m9SC2DbWxTrlTxJr12p0", firstName: "test user", Title: "design job", empname: "Rakesh", …}

Hope this oneliner helps

const arr = [{jobid: "atA3Qi4BJu01VrUasiSX", id: "I1bncvyBsjbu7ePdPvYt", firstName: "Krishnakumar K R", Title: "design job", empname: "Rakesh"},
{jobid: "atA3Qi4BJu01VrUasiSX", id: "MDxEVS2hKftDrrPXsSWL", firstName: "test Candidate", Title: "design job", empname: "Rakesh"},
{jobid: "atA3Qi4BJu01VrUasiSX", id: "Mmu7oiAoCNcaU2ZWlLeS", firstName: "Rakesh", Title: "design job", empname: "Rakesh"},
{jobid: "atA3Qi4BJu01VrUasiSX", id: "m9SC2DbWxTrlTxJr12p0", firstName: "test user", Title: "design job", empname: "Rakesh"},
{jobid: "nCBNJ1yEn4EaGLR4BHDc", id: "1GMZpFhcOyDSt1KG4abK", firstName: "mohammed basheer", Title: "test job emp", empname: undefined},
{jobid: "nCBNJ1yEn4EaGLR4BHDc", id: "MDxEVS2hKftDrrPXsSWL", firstName: "test Candidate", Title: "test job emp", empname: undefined},
{jobid: "nCBNJ1yEn4EaGLR4BHDc", id: "Mmu7oiAoCNcaU2ZWlLeS", firstName: "Rakesh", Title: "test job emp", empname: undefined},
{jobid: "atA3Qi4BJu01VrUasiSX", id: "I1bncvyBsjbu7ePdPvYt", firstName: "Krishnakumar K R", Title: "design job", empname: "Rakesh"},
{jobid: "atA3Qi4BJu01VrUasiSX", id: "MDxEVS2hKftDrrPXsSWL", firstName: "test Candidate", Title: "design job", empname: "Rakesh"},
{jobid: "atA3Qi4BJu01VrUasiSX", id: "Mmu7oiAoCNcaU2ZWlLeS", firstName: "Rakesh", Title: "design job", empname: "Rakesh"},
{jobid: "atA3Qi4BJu01VrUasiSX", id: "m9SC2DbWxTrlTxJr12p0", firstName: "test user", Title: "design job", empname: "Rakesh"},
{jobid: "nCBNJ1yEn4EaGLR4BHDc", id: "1GMZpFhcOyDSt1KG4abK", firstName: "mohammed basheer", Title: "test job emp", empname: undefined},
{jobid: "nCBNJ1yEn4EaGLR4BHDc", id: "MDxEVS2hKftDrrPXsSWL", firstName: "test Candidate", Title: "test job emp", empname: undefined},
{jobid: "nCBNJ1yEn4EaGLR4BHDc", id: "Mmu7oiAoCNcaU2ZWlLeS", firstName: "Rakesh", Title: "test job emp", empname: undefined}]

let pp = arr.filter( (ele, ind) => ind === arr.findIndex( elem => elem.jobid === ele.jobid && elem.id === ele.id))

console.log(pp)
