# Invoke vs Call a Function – Learn the Difference

"Invoke a function" and "Call a function" are popular programming terms. But what exactly do they mean? Let's find out.

## What Does "Invoke a Function" Mean in Programming?​

"Invoke a function" means executing a function to retrieve its value.

### How to invoke a function​

We use the function's name and an invocator (()) to invoke a function.

Here's the syntax:

functionName();

### Examples​

Below are examples of how to invoke a function.

#### How to invoke a function without an argument​

// Define a function:function multiplyNumbers() {  return 3 * 100;}// Invoke the multiplyNumbers function:multiplyNumbers();// The invocation above will return: 300

The snippet above invoked the multiplyNumbers function without passing any argument to its parameters.

## Get creative with your projects

Brainstorm, sketch, and create wireframe design mockups.

#### How to invoke a function with two arguments​

// Define a function:function multiplyNumbers(a, b) {  return a * b;}// Invoke the multiplyNumbers function:multiplyNumbers(3, 100);// The invocation above will return: 300

The snippet above invoked the multiplyNumbers function while passing two arguments (3 and 100) to its parameters (a and b).

## What Does "Call a Function" Mean in Programming?​

"Calling a function" means to call for a function without retrieving its value.

### How to call a function​

We use the function's name only to call a function.

Here's the syntax:

functionName;

### Example​

// Define a function:function multiplyNumbers(a, b) {  return a * b;}// Call the multiplyNumbers function:multiplyNumbers;// The call above will return:ƒ multiplyNumbers(a, b) {  return a * b;}

The snippet above used the function's name (multiplyNumbers) to call the function without retrieving its value.

## Overview​

"Function invocation" invokes a value from a function. But "function calling" calls for the function.
