Answer / Sumit Kumar Srivastav
"Reading and writing files in JavaScript can be done using the FileReader API. To read a file, you can create a new FileReader object, set its onload event with a callback function, call the readAsText() method to read the file as text, and access the contents through the onload event's target. Here's an example: let reader = new FileReader(); reader.onload = function (event) { console.log(event.target.result); }; reader.readAsText(file); To write a file, you can create a new Blob object with the desired content, create a new File object using a user-provided name and the Blob, and use the saveAs() method to download the file: let blob = new Blob([content], { type: "text/plain" }); let file = new File([blob], "myFile.txt", { type: "text/plain" }); saveAs(file);"
