Question

Which statement about a function in JavaScript is true?

A) Functions cannot be assigned to variables.
B) Functions can only take a fixed number of arguments.
C) Functions in JavaScript are objects and can be assigned to variables.
D) Functions cannot have return values.

Answer 1

The correct statement about a function in JavaScript is that functions are objects and can be assigned to variables. They can have properties and methods, can be passed around, and do not require a fixed number of arguments. The correct answetr is option C.

Step-by-step explanation:

The correct statement about a function in JavaScript is: C) Functions in JavaScript are objects and can be assigned to variables. Functions in JavaScript are indeed versatile and have many useful features. They can be treated like objects, which means they can be assigned to variables, passed as arguments to other functions, and even have properties and methods assigned to them.

For example:

const greet = function(name) {
return 'Hello ' + name + '!';
};
console.log(greet('Alice'));

This defines a function that greets a person by name, and assigns it to the variable greet. When you call greet('Alice'), it returns 'Hello Alice!'. Notice how the function is assigned just like any other value to the variable.

Contrary to options A, B, and D, functions in JavaScript can certainly have return values, and they do not need to have a fixed number of arguments thanks to the arguments object that allows you to access all arguments passed to the function.
