Lesson
legacy-mindset
This lesson teaches Legacy mindset: the concepts, APIs, and habits you need before advancing in AngularJS.
Without Legacy mindset, you will struggle to read or extend AngularJS codebases and playground exercises.
You will apply Legacy mindset in contexts like: Long-lived intranet apps, government portals, and codebases not yet moved to Angular, React, or Vue.
Write JavaScript for AngularJS 1.8, click Run—register modules/controllers, then mountApp(moduleName, templateHtml) in #ng-app; printOutput feeds the terminal.
At the start of the track—complete before JSX-heavy lessons that assume you understand the playground.
Treat AngularJS as maintenance literacy: read safely, patch incrementally, and plan migration—not greenfield framework choice.
Can you explain this lesson in 30 seconds without reading notes?
