Hi,

Welcome to the world of ServiceNow development! It's great that you're interested in starting this journey. Since you're new to programming and ServiceNow, here’s a step-by-step guide to help you get started:

1. Understand ServiceNow Basics

• Learn What ServiceNow Is: ServiceNow is a cloud-based platform for IT service management (ITSM) and automating business workflows. It uses a mix of coding and low-code/no-code configurations.
• Familiarize Yourself with the Platform: Sign up for a free ServiceNow Developer Account at developer.servicenow.com. This gives you access to a personal development instance where you can practice and learn.

2. Learn the Required Programming Languages

ServiceNow primarily uses:

• Javascript: It’s the core scripting language for client-side and server-side development in ServiceNow. Start by learning the basics of JavaScript (variables, functions, loops, etc.).
• HTML & CSS: These are used for designing custom interfaces and portals. While not mandatory, basic knowledge helps in UI/UX tasks.
• Optional: Learn about REST APIs as they are frequently used in integrations with ServiceNow.

3. Explore ServiceNow-Specific Skills

• Understand Glide API: ServiceNow uses Glide API for server-side scripting.
• Client Scripts and Business Rules: Learn how to write client-side scripts (executed in the browser) and server-side business rules (executed on the server).
• UI Policies, Workflows, and Flow Designer: These are essential for automating tasks.
