Certifications
Certifications play a significant role in validating an Extjs Developer's expertise, especially for employers seeking to ensure a high standard of technical competency. While Extjs itself does not have an official certification program from Sencha (the creators of Extjs), several industry-recognized certifications and training programs are highly relevant for Extjs Developers.
Sencha Training and Certification: Sencha, the company behind Extjs, offers official training courses such as "Extjs Fundamentals" and "Advanced Extjs." While these are not formal certifications, completion of these courses demonstrates a solid understanding of the framework, best practices, and advanced features. Employers value candidates who have invested in official training, as it indicates a commitment to mastering the platform.
