How to change one array same as another array

I have two arrays. I want compare modified array with original array and I want to change the modifid array same as the original array. position want to be same also

I expecting output is,

const modified = [
                          {label: 'cover1', formUid: 1045},
                          {label: 'cover2', formUid: 211},
                          {label: 'cover3', formUid: 204},
                          {label: 'cover4', formUid: 258},
                          {label: 'cover1', formUid: 1045},
  ]

but now I am getting like this,

const modified = [
                          {label: 'cover2', formUid: 211},
                          {label: 'cover3', formUid: 204},
                          {label: 'cover4', formUid: 258},
                          {label: 'cover1', formUid: 1045},
      ]

here is my try,

const original = [
                          {label: 'cover1', formUid: 1045},
                          {label: 'cover2', formUid: 211},
                          {label: 'cover3', formUid: 204},
                          {label: 'cover4', formUid: 258},
                          {label: 'cover1', formUid: 1045},
                           
                       ];
                       
      const modified = [
                           {label: 'cover4', formUid: 258},
                          {label: 'cover2', formUid: 211},
                          {label: 'cover3', formUid: 204},
                          {label: 'cover1', formUid: 1045},
                           {label: 'cover1', formUid: 1045},
      ]
    
    function testFunc(original , modified){
    let originalCopyForPosision;
  
    originalCopyForPosision = [...original];
         
         modified.forEach((element,idx) => {
             
              let targetIndex = originalCopyForPosision.findIndex(e => e.formUid === element.formUid)
             
              if(idx === targetIndex){
              return
              }else{
             
                if(targetIndex > 0){
                  modified.splice(targetIndex,  1);
                  modified.splice(idx,0,element);
                }
               
              }
    
         })
    
    document.getElementById("originalArray").innerHTML = JSON.stringify(original);
    document.getElementById("modifiedArray").innerHTML = JSON.stringify(modified);
    
    }testFunc(original,modified)
