Functions in JavaScript - Function methods length

The length() method is a function method in JavaScript that can be used to determine the number of arguments passed into a function. It returns the number of named arguments in the function declaration. The arguments() method, on the other hand, is not a function method but rather an array-like object that contains all the arguments passed into the function. The call() and bind() methods are used to invoke a function with a specified context and are not used for determining the number of arguments.

function myFunction(name, age) {
  // ...
}
const numberOfArguments = myFunction.length;

console.log(`The number of arguments passed to myFunction() is: ${numberOfArguments}`); // Output: The number of arguments passed to myFunction() is: 2
