KnockoutJS VS Polymer

Polymer is a powerful library focused on modern web standards and custom elements, making it ideal for building reusable, component-based applications. In contrast, KnockoutJS is a lightweight library that excels in data binding and the MVVM pattern, making it more suitable for simpler applications. Both have their strengths, but the choice between them largely depends on the complexity and requirements of the project.
