Whether you're just getting started or are looking to sharpen your skills, these insights will provide a considerable edge in your day-to-day work.

1. Master the Scripting Basics

Understanding scripting fundamentals can significantly improve your ability to customize and automate processes in ServiceNow. Focus on learning JavaScript, as it is the core scripting language used in ServiceNow. Develop a strong command over the basic scripting concepts such as objects, arrays, loops, and even closures, which are crucial when working on client scripts and business rules. Spend time practicing ServiceNow's scripting tools and environments, such as Script Include and GlideRecord.

2. Leverage ServiceNow's Learning Resources

ServiceNow provides comprehensive documentation and a range of learning resources. The ServiceNow Developer Program and Now Learning platform offer valuable courses and hands-on tutorials. Regularly participate in the ServiceNow Community to connect with other developers, gain insights, and stay updated with platform releases. Continuous learning is key to staying proficient in the evolving environment of ServiceNow.

3. Use Update Sets Wisely

Update Sets ensure that configuration changes are consistently tracked. Develop a practice of grouping related changes into meaningful sets to facilitate easy management and migration between instances. Always test changes in a development instance before deploying them into production. This practice reduces the risk of overwriting important data inadvertently.

4. Understand the Data Schema

A profound understanding of ServiceNow's data schema is essential for effective development. Familiarize yourself with the Common Services Data Model (CSDM) and CMDB data model. Pay attention to how tables interact and the relationships between those tables. Utilize ServiceNow's schema map feature to visually understand the tables' interconnections.

5. Implement Best Practices in Coding

Adhering to best coding practices promotes code simplicity, readability, and maintenance. Name variables and functions descriptively, write modular code, and document your code comprehensively. Use comments to explain complex logic or computation. Moreover, use version tracking tools to manage versions of your code and scripts efficiently.

6. Automate with Workflow and Flow Designer

Mastering automation tools like the Workflow editor and Flow Designer can massively boost your efficiency. These tools help automate repetitive tasks and streamline complex processes. Understand how to design workflows that integrate with ServiceNow's powerful orchestration capabilities, and practice creating reusable subflows for commonly executed tasks.

7. Advanced Knowledge of GlideRecord

GlideRecord is pivotal in querying and manipulating records in the database. A deep understanding of its methods can enhance your data handling capabilities. Practice writing efficient GlideRecord queries and avoid performance issues by reducing unnecessary queries or filtering data correctly. Consider using ‘getRowCount’ to manage large datasets effectively.

8. Utilize Plugins and Scoped Applications

Plugins and scoped applications extend ServiceNow’s capabilities beyond its core features. Identify and implement essential plugins that align with your business goals. Scoped applications provide a secure space to develop and distribute applications, ensuring separation and protection of custom development. Learn to create and distribute scoped applications effectively.

9. Prioritize Security Practices

Ensure security is a core part of your development strategy. Implement security roles appropriately, write secure scripts to prevent injection attacks, and regularly perform security audits. Being vigilant about security not only protects your instance but enhances your organization's overall security posture.

10. Network and Engage with the ServiceNow Community

Engaging with the ServiceNow community provides unparalleled support and opportunities to share knowledge. Participate in forums, webinars, and local user groups. Contributing to these platforms not only aids personal growth but can provide novel solutions to common challenges faced during ServiceNow development.
