In JavaScript, you can access all arguments passed to a function — even if they are not explicitly listed as parameters — using the arguments object or rest parameters (...args).
Example using arguments object:
function logArguments(a, b) {console.log("First argument:", arguments[0]);console.log("Second argument:", arguments[1]);console.log("Total arguments passed:", arguments.length);}logArguments(10, 20, 30);// Output:// First argument: 10// Second argument: 20// Total arguments passed: 3Copied!âś•CopyHere, arguments is an array-like object available inside all non-arrow functions. It contains indexed values of all passed arguments and a length property, but lacks array methods like .map() or .forEach() unless converted to a real array.
