Creating Loops

Video tutorial available in the Zapbot dashboard

In this guide, we demonstrate how to implement a dynamic loop to collect guest names for a restaurant reservation chatbot.

Overview

We walk through setting up the chatbot to request the number of guests, and then, using JavaScript, create a list based on this number.

How It Works

1. Ask for count: Request the number of guests from the user
2. Create a list: Use the 'Shift' set variable value to iterate through this list
3. Collect information: Store each guest's name through the loop

Implementation

Despite the lack of a specific loop block in the platform, you can create loop-like behavior through custom code using the Set Variable block.

Key Concepts

• Use JavaScript in the Set Variable block to manage iteration
• The 'Shift' operation removes and returns the first element of an array
• Connect blocks to create the looping behavior
• Use conditions to check when the loop should end

Example: Guest Name Collection

1. Ask "How many guests will be attending?"
2. Store the number in a variable
3. Create an array with that many empty slots
4. Loop through each slot, asking for a guest name
5. Store all names in a results array
