# Function Setting
## Function Editor
The function editor is an area where you can write, run, add, delete, and name functions. Each function has its own code area and code output, and its code does not affect the other functions.
### Code area
The code area is where you are going to write down your function code. When you type **spacebar**, the auto complete dropdown is given. The Auto complete dropdown suggests functions by using the keyword you write after typing spacebar. Use **up/down arrow** keys to get to the item you want to add and press **enter** to add the function into the code area.
You can run and get the result of the functions as follows:
1. Select a function tab you want to code.
2. After code is completely written, click **Run** button.
3. At the **Code Output** area below the code editor, you'll find out the result.
4. You can visualize the result in chart at **Visualization Setting** tab.
### Code Output
When you click a **run** button after filling out the functions, you can get the result of every function you made. And the table filled with the result can be seen at the code output.
If the result is not shown or the error comes out, then it means that your function may has an error somewhere. Fix your function code and run again to get the right result.
