JavaScript
let filename = "dog.pdf";
let parts = filename.split('.'); // Split by dot to get ["dog", "pdf"]
parts.pop(); // Remove the last element ("pdf"), leaving ["dog"] behind
let filenameWithoutExtension = parts.join(''); // Join back without the dot
console.log(filenameWithoutExtension); // Output: "dog"
