Snippet from article: const binaryString = window.atob(fileResponseData); const bytes = new Uint8Array(binaryString.length); const mappedData = bytes.map((byte, i) => binaryString.charCodeAt(i)); const blob = new Blob([mappedData], { type: 'application/pdf' }); btoa and atob are deprecated. For example, users can upload images, videos, etc on Facebook, Instagram, etc. Now we will use file reader and use onload event in file reader than we will get image url and we need to remove some text to get the base64 string and store in variable named base64String and print on console. here is the code: (I attempted the the bottom part of the code the second function) Make sure you use the correct path here. , , , and sources are copied into the 'Blob' and can therefore be safely modified after the 'Blob' is created.
