Esquery is a valuable tool for developers working with ECMAScript Abstract Syntax Trees (ASTs). It provides a CSS selector-like query language, simplifying the process of traversing and extracting specific nodes from complex AST structures. Comparing versions 0.1.0 and 0.2.0, we observe a relatively short time span between releases, suggesting rapid iteration and potentially bug fixes or minor feature enhancements. Both versions share the same core description, indicating a consistent purpose: querying ECMAScript ASTs. The developer dependencies remain the same, using "jstestr" for testing. The licensing is BSD, offering flexibility in how the tool can be used and distributed. Both versions are authored by Joel Feenstra, and the repository URL is consistent, pointing to the GitHub repository. The most apparent difference lies in the version and releaseDate fields. Version 0.2.0 was released a few days after 0.1.0, highlighting the recency of the updates.
For developers, esquery's utility comes from its ability to greatly simplify AST manipulation. Rather than writing verbose code to walk the AST manually, developers can use familiar CSS selectors to pinpoint the nodes they need. If you are using esquery in your project, upgrading from 0.1.0 to 0.2.0 is recommended given the relatively narrow time window between the version releases. It might fix some bugs and add minor features. As a query library providing a CSS-like query language for ECMAScript ASTs, esquery can be an absolute gain to your workflow.
