# Functions

A function is a block of code designed to perform a specific task and executed when "something" invokes it. More info about functions can be found in the[ functions](/js-101/functions.md) chapter.

### 📝 Task:

* [ ] Write a program to create a function named `isOdd`that passes a number `45345` as an argument and determines whether the number is odd or not.
* [ ] Call this function to get the result. The result should be in a boolean format and should return `true` in `console`. 

### 💡 Hints:

* Visit the [functions](/js-101/functions.md) chapter to understand functions and how to create them.
