Removing duplicates fromarray of objects

Question

I have an array of objects as myData which consists of the below JSON structure:

const data = {
 myData: [
 { Type: 'REAL', Tenure: '12', Name: 'WEBPAGE' },
 { Type: 'REAL', Tenure: '24', Name: 'SERVER' },
 { Type: 'REAL', Tenure: '12', Name: 'WEBPAGE' },
 ],
};

I want to get rid of duplicate entries by keeping performance in mind as this array could be of length 1000+ using Javascript.

The Expected Output that I am looking for is as follow since myData[0] && myData[2] are duplicate here:

const result = {
 myData: [
 { Type: 'REAL', Tenure: '24', Name: 'SERVER' },
 { Type: 'REAL', Tenure: '12', Name: 'WEBPAGE' },
 ],
};

• DecPK: First of all, How do you consider that two objects are duplicates? Are you matching all properties or just specific property?
