code

let arr = [{service:"test", program:[{pg:123, ag:123}]},
           {service:"test", program:[{pg:123, ag:123}]},
           {service:"test1", program:[{pg:1234, ag:1234}]}]
           
const result = arr.reduce((unique, o) => {
          if (!unique.some(obj => obj.service === o.service)) {
            unique.push(o);
          }
          return unique;
        }, []);

console.log(result)

Here I am trying to compare the array of objects and remove duplicates but I was able to compare only first level of array of object. I need to compare the "programs" array of objects as well.

Expected Output

[{service:"test", program:[{pg:123, ag:123}]},
 {service:"test1", program:[{pg:1234, ag:1234}]}]

What is `tempObj`? What is `programs`? – trincot May 30 '22 at 17:21
sry tempobj is the array. I have updated the code. program is another key-value pair which holds array of objects as. value – Shruthi Reddy May 31 '22 at 16:06

Here I need to check for same program and same service values and remove duplicates @trincot – Shruthi Reddy May 31 '22 at 16:41
Yes, your question was closed, because similar questions already have answers. See at the top. But your question's code showed no attempt to do the same on programs. Just apply the same logic to those arrays as well. – trincot May 31 '22 at 16:49
