When aspiring to be a Backend Developer, it is important to learn multiple programming languages and frameworks, not just rely on JavaScript.
JavaScript for backend development is not as popular in the job market, especially for beginners, and it is more of a 'nice to have' skill.
Recommended languages and frameworks for backend development include PHP (Laravel), Java (Spring Boot), Python (Django), and Go (popular, but framework name unknown).
In addition to language and framework knowledge, it is crucial to learn SQL queries, version control with Git, and other tools like Docker, AWS, GCP, and CI/CD.
