Ember.js

Ember.js is a profoundly historic, intensely powerful, and heavily opinionated platform that operates as a colossal titan in the "Massive, Long-Lived Enterprise Web Applications" sector. While React and Vue change their architectures constantly, causing massive rewrite headaches for enterprises, Ember built its reputation on "Stability without Stagnation." It provides an unshakeable, highly structured environment. The absolute core differentiator of Ember is its "Convention over Configuration and Ember CLI." Ember enforces strict rules. There is exactly one way to do routing. There is exactly one way to handle data (Ember Data). If you hire a new Ember developer, they can look at a 5-year-old codebase and instantly understand it because it follows the exact same conventions. Its CLI tool is legendary for generating and testing massive codebases. Because it refuses to chase shiny trends, offering staggering backwards compatibility and a highly robust data layer, it remains the heavy-duty engine behind massive, complex web applications like Apple Music, LinkedIn, and Discourse.
