handleDownload()Function is added as an event handler (onclick) to the button so that the user can download the file. The user can download but the file is corrupted. How do we prevent file corruption?

function handleDownload(){ const domain = window.location.origin; const url =`${domain}/images/athar.pdf` fetch(url). then(response=>response.blob()). then(blob=>{ const blobURL= window.URL.createObjectURL( new Blob([blob])) const filename = 'athar.pdf' const aTag = document.createElement('a') aTag.href=blobURL aTag.setAttribute('download',filename) document.body.appendChild(aTag) aTag.click() aTag.remove() }). catch(e=>console.log(e)) }
