5 alternatives to JavaScript

thealgorithms/javascript — Algorithms and Data Structures implemented in JavaScript for beginners, following best practices. (34,281 stars, GPL-3.0, dev-tools, integration, security).

These are the closest projects in the JustClaw-It index that we serve licence-cleared code from, ranked by relevance and by our code-quality score (1–10, the mean over each repo's graded components: completeness, code quality, deployability, reusability, strategic value). JustClaw-It does not serve code from thealgorithms/javascript itself (licence class: strong-copyleft), so these alternatives are the licence-cleared route.
