Minimal templating on steroids.
Role in this project:Front-end Developer
Front-end DeveloperContributions:9 commits, 3 PRs, 4 pushes in 2 months
Contributions summary:Lonni primarily focused on improving the testing framework for the Handlebars.js library. They added tests for nested inline partials and ensured correct rendering of partial blocks. Moreover, they updated the test structure by utilizing XML-like tags to improve readability, rather than using dot delimiters. They also fixed a bug related to the rendering of nested `@partial-block` calls by modifying runtime code.
