# Functions Block

### Functions related blocks are explained below

Functions are a set of codes that can be called repeatedly for a particular operation. The function is executed when something invokes it (calls it). In the EdgeReady Cloud, these functions are available as individual blocks.

There are two types of functions: One that returns a value and one that does not return a value.

In these blocks:

- Function **parameters** are listed inside the blocks in the function definition.
- Function **arguments** are the **values** received by the function when it is invoked.
- Inside the function, the arguments (the parameters) behave as local variables.

## Create Function:

This block helps users create new functions. The functions can be created:

- Without Return Value
- With Return Value
- As a Global Function or local function

| **Input** | **Output** | **Block Layout** | **Generated Code** |
| --- | --- | --- | --- |
| Function Name Text, Arguments Name text, set as a global function checkbox, allow statements checkbox, Function statements. Return for a function of any type. | This block will create a function definition depending upon input arguments and the choice of whether they are global. | ![](https://cdn.document360.io/718af901-247b-46be-8ace-83da21839237/Images/Documentation/image-1620906181931.png) ![](https://cdn.document360.io/718af901-247b-46be-8ace-83da21839237/Images/Documentation/image-1620906208072.png) ![](https://cdn.document360.io/718af901-247b-46be-8ace-83da21839237/Images/Documentation/image-1620906225723.png) ![](https://cdn.document360.io/718af901-247b-46be-8ace-83da21839237/Images/Documentation/image-1620906247786.png) | ```javascript var Name = function () { } window.Name = function (x, y) { } var Name2 = function () { return ''; } ``` |

#### 

## Invoke Function:

Function invocation occurs when:

- When an event occurs (when a user clicks a button)
- When it is invoked (called) from another code block
- Automatically (self invoked)

In the EdgeReady Cloud, the function block is invoked:

- With Return Value
- Without Return Value
- As a Global Function

| **Input** | **Output** | **Block Layout** | **Generated Code** |
| --- | --- | --- | --- |
| Function Name Text, Arguments variable or any type value. | Call the function definition using name and arguments. | ![](https://cdn.document360.io/718af901-247b-46be-8ace-83da21839237/Images/Documentation/image-1620906325038.png) ![](https://cdn.document360.io/718af901-247b-46be-8ace-83da21839237/Images/Documentation/image-1620906373921.png) ![](https://cdn.document360.io/718af901-247b-46be-8ace-83da21839237/Images/Documentation/image-1620906393411.png) | ```javascript Name('', ''); Name2() ``` |

#### 

## Function Definition with an input statement:

In this function definition, an input statement is provided. The input function is used to request the user to provide necessary input in a designated input field. The value is then returned as the result of the function that is stored in the declared variable.

| **Input** | **Output** | **Block Layout** | **Generated Code** |
| --- | --- | --- | --- |
| Arguments variable or any type value, Function statements. Return for a function of any type. | Create a function definition with return and input statements that store to a variable or as a value. | ![](https://cdn.document360.io/718af901-247b-46be-8ace-83da21839237/Images/Documentation/image-1620906434074.png) ![](https://cdn.document360.io/718af901-247b-46be-8ace-83da21839237/Images/Documentation/image-1620906452217.png) | ```javascript function () { }; ``` |

#### 

## Function Definition without a statement:

In this function definition block, there is no input that is requested from the user. However, this function can return a value based on the nature of the action triggered and parameters defined to invoke the function.

| **Input** | **Output** | **Block Layout** | **Generated Code** |
| --- | --- | --- | --- |
| Arguments variable or any type value, Return for a function of any type. | Create a simple function definition with return only that store to a variable or as value. | ![](https://cdn.document360.io/718af901-247b-46be-8ace-83da21839237/Images/Documentation/image-1620906599406.png) | ```javascript function () { return ''; }; ``` |
