Need Guidance on Course for Web Development Career Switch

Hello, I am currently working as an SEO Intern but want to transition into software/web development. To improve my chances of getting a job, I’m considering taking a relevant course. Could anyone suggest which course would be most helpful for landing a good opportunity? Also, is learning Data Structures and Algorithms (DSA) necessary for web development roles, or would focusing on project-based learning be equally effective? I want to ensure I choose the right path to break into a good company. Any insights or recommendations from experienced developers would be greatly appreciated. Thanks in advance!
