Provides helper functions for working with JavaScript Function call, apply, and bind, intended for use with `call-bind`. It is mainly meant to be used directly by `call-bind` and `get-intrinsic`, with a README suggestion to use `call-bind` instead unless you have a specific reason.
This source does not appear to be actively maintained, last upstream push was 2025-02-12, about 16 months ago relative to 2026-06-09.
Last release:
call-bind provides utilities to robustly create a bound function using `.call.bind()`. It’s useful in JavaScript codebases that need consistent function binding and access to pre-bound methods like `call-bind/callBound`.
Actively maintained: Yes, the repo has recent updates, with the latest upstream push on 2026-04-09 and a tagged update v1.0.9 on 2026-04-09.
Last release:
Browserslist lets front-end tools share a single set of target browsers and Node.js versions. It reads configuration from package.json or .browserslistrc, supports queries like “last 2 versions,” and uses caniuse data so tools such as Autoprefixer, Babel preset-env, and stylelint can automatically determine which browser targets to apply.
Actively maintained: Recent activity is very recent and ongoing (last upstream push 2026-08-08, with updates released again on 2026-08-08 and through 2026-07), indicating continued stewardship rather than dormancy.
Last release:
This JavaScript library implements brace expansion syntax similar to sh/bash (as documented for Bash). It provides an `expand(str, [options])` function that returns an array of all valid expanded strings, with an optional `max` limit to cap the number of generated expansions.
The source appears actively maintained, with the last upstream push on 2026-08-09 and multiple recent package updates in 2026 (notably v1.1.15, v2.1.1 in late May 2026).
Last release:
baseline-browser-mapping provides browser version data for the W3C WebDX Baseline feature sets. Use getCompatibleVersions() to get the minimum compatible browser versions for Baseline Widely available and Baseline year features, or use getAllVersions() to retrieve support details for multiple Baseline feature sets across browser versions. It is updated frequently to stay current with underlying browser-compatibility data, and can warn if the installed data is older than about 2 months.
Actively maintained, with very recent GitHub activity (last upstream push 2026-07-22) and a new version shortly after (v2.11.0 on 2026-07-21), plus additional updates in 2026 (not just older history).
Last release:
balanced-match finds the first non-nested, matching pair of delimiter characters (or patterns), such as `{` and `}` or `<b>` and `</b>`, in a string. It returns the match positions and surrounding text (pre, body, post), or `undefined` if no match is found, and can also use regular expressions.
Active maintenance is evident, with an upstream push on 2026-05-26 and multiple package updates released in 2026 (v4.0.2 on 2026-02-09, v4.0.3 on 2026-02-18, v4.0.4 on 2026-02-22).
Last release:
bail is a small ESM-first utility that throws a provided error, or throws the given error parameter when one is passed. It is useful when you are done repeatedly writing `if (error) throw error` in scripts where errors are unlikely but possible.
Maintenance status: Quiet and likely in maintenance mode, upstream last push was 2022-11-20, and the most recent published updates are from 2021-11-07, with no evidence of active recent work as of 2026-06-09.
Last release:
axobject-query provides programmatic access to an approximate Chrome AXObject Model and maps AXObject concepts to the WAI-ARIA 1.1 roles model. It includes utilities like AXObjects for working with the mapped objects and their related HTML and ARIA concepts, useful when you need a semantic layer representation as exposed to assistive technology.
Maintenance status: Evidence suggests the repo is not actively maintained now. The last upstream push was 2024-12-17, and no further updates are shown after that relative to 2026-06-09 (suggesting a quiet or maintenance-mode period rather than ongoing development).
Last release:
Axe-core is an accessibility testing engine for websites and other HTML-based user interfaces. It provides rules for WCAG 2.0, 2.1, and 2.2 (levels A, AA, AAA) plus best practices, and can be integrated into automated Web UI tests to detect accessibility issues.
Actively maintained: GitHub upstream push occurred on 2026-08-12, and updates are continuing in 2026 (not a long gap), with the latest entry being v4.13.0 on 2026-08-05.
Last release:
This package returns an array of Typed Array names that are available in the current JavaScript environment. It is useful for runtime feature detection before using specific Typed Array types (for example, checking support for Float16Array or BigInt64Array).
Actively maintained is unclear, but there is evidence of recent repository activity: the upstream last push was 2026-03-10, while the latest documented package update was v1.0.7 on 2024-02-19.
Last release:
async-function is a small package that returns the normally hidden AsyncFunction constructor when it is available. It is useful if you need to create async functions dynamically (for example, by calling new AsyncFunction(...) with a function body).
The source appears to be quiet-to-low activity: the provided evidence shows a last upstream push on 2026-04-21, but the most recent documented update/tag is v1.0.0 from 2025-01-23, with no newer update summaries included.
Last release:
Astring is a tiny, fast JavaScript code generator that turns an ESTree-compliant AST into JavaScript source code. It’s useful for projects that need to generate code (optionally with source maps and comments) from ASTs produced by parsers like Acorn or Meriyah.
Maintenance status: The most recent upstream activity was 2024-12-01, and the newest recorded GitHub update is v1.9.0 on 2024-08-25, so relative to 2026-06-09 the project appears quiet and likely in maintenance mode rather than actively maintained.
Last release:
Provides Flow type definitions for the JavaScript AST (based on benjamn/ast-types), so you can import `ast-types-flow` types like `Node` in Flow-typed code. It includes a transform that compiles “extends” relationships expressed in comments into disjoint union types to help model different AST node shapes accurately.
The source appears not actively maintained, with the last upstream push on 2023-04-15, which is over 3 years ago relative to 2026-06-09.
Last release:
ES spec-compliant shim for `ArrayBuffer.prototype.slice`, provided for JavaScript environments where it may be missing or unsupported. Useful if you need to create sliced `ArrayBuffer` instances consistently, by calling the `shim` method when `ArrayBuffer.prototype.slice` is unavailable.
This GitHub update source appears to be quiet rather than actively maintained, with the last upstream push on 2024-12-15, and no evidence of activity since then (as of 2026-06-09).
Last release:
Provides an ESnext spec-compliant shim or polyfill for `Array.prototype.toSorted`, letting you use the proposed `toSorted` behavior in environments down to ES3. It can be used either as a function that takes the input array, or via `shim()` to install `Array.prototype.toSorted` when it is missing.
Maintenance status: The last upstream push and published update are from 2024-06-03, and there have been no evidence-backed updates since then, so the project appears quiet or in maintenance mode rather than actively maintained as of 2026-06-09.
Last release:
An ES2019 spec-compliant `Array.prototype.flatMap` shim, polyfill, or replacement designed to work in environments down to ES3. Useful for adding `flatMap`-style behavior to older JavaScript engines, with a API that exports a function taking the array as the first argument (because `flatMap` depends on the receiver `this`).
Maintenance status: Appears not actively maintained in terms of published package updates, with the most recent published update v1.3.3 dated 2024-12-16 (about 1.5 years ago as of 2026-06-09). However, there was an upstream push on 2025-12-30, suggesting some ongoing repository activity despite no corresponding new published updates shown here.
Last release:
This is an ES2019 spec-compliant `Array.prototype.flat` shim or polyfill for flattening nested arrays, implemented to work in environments as old as ES3. It provides a main export that takes the target array as the first argument and can also supply a `shim()` that replaces or matches `Array.prototype.flat` behavior when needed.
The source appears maintained, with the most recent tagged update v1.3.3 dated 2024-12-15, and an additional upstream push on 2025-12-30, though detailed release notes are not provided for recent updates.
Last release:
An ESnext spec-compliant shim or polyfill that provides `Array.prototype.findLastIndex`, including in older ES3-supported environments. Useful for codebases that need consistent `findLastIndex` behavior and can either call the exported function with an array argument or use `.shim()` to ensure `Array.prototype.findLastIndex` is available.
Maintenance status: Appears to be in maintenance mode rather than actively maintained, with the most recent update on 2025-03-14 and no evidence of updates since then (as of 2026-06-09 this is about 15 months ago).
