For JavaScript source quality, JSHint is the clearest fit in this group. For vulnerable libraries, use Retire.js; for dependency security and license checks, consider Sandworm Audit. Clair focuses on container images, while CodeChecker stores and visualizes reports from analyzers that include JavaScript analysis. These tools address different parts of a JavaScript codebase, so choose by what you need to inspect.

Best Static Analysis Tools For JavaScript
1. JSHint: Best For JavaScript Code Quality Checks
JSHint is the most direct choice here when you want feedback on JavaScript source itself. Its documented checks include cyclomatic complexity, unused and undefined variables, development code such as console use, and newer JavaScript features including ES6. The project identifies itself as a JavaScript code quality tool and lists version 2.13.6.
Use it to flag a growing function’s complexity or catch a misspelled variable before the code ships. The available facts do not establish editor, build-system, or CI integrations, so check the JSHint site for the workflow details you need.
2. Retire.js: Best For Finding Vulnerable JavaScript Libraries
Retire.js addresses a different risk: using JavaScript libraries or Node modules with known vulnerabilities. It offers a command-line scanner, Chrome and Firefox extensions, and a Burp and ZAP plugin. It can scan a web app or Node app, and the browser extensions scan visited sites for insecure library references and warn in the developer console.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Choose it when you need to identify vulnerable library use in an app or inspect sites as you browse. The documented goal is detection of versions with known vulnerabilities; the available information does not establish broader source-code quality checks.
3. Sandworm Audit: Best For JavaScript Dependency And License Audits
Sandworm Audit analyzes JavaScript and PHP supply chains, including packages and dependencies, for security vulnerabilities, license issues, and metadata problems. Its documented package-manager support includes npm, Yarn, and pnpm. You can run it from a terminal or in CI and Git hook workflows, and it produces JSON issue and license reports, CSV dependency data, and dependency tree and treemap visualizations.
Rank #2
- 5-in-1 USB-C Hub: Experience comprehensive connectivity featuring a Power Delivery input, two USB-A 2.0 ports, a USB-A 3.0 port, and an HDMI port. (Note: The USB-C power delivery input port is only for connecting an external wall charger to power your laptop and cannot power peripheral devices.)
- 90W Pass-Through Charging: Achieve optimal charging with 90W pass-through power to your laptop, supported by a total input of 100W, with the hub reserving 10W for operational efficiency. (Note: Wall charger not included.)
- Quick Data Transfers: Accelerate your productivity with rapid data transfers using a high-speed 5Gbps USB 3.0 port and two 480Mbps USB 2.0 ports.
- 4K HDMI Display: Enhance your visual experience with a hub capable of delivering 4K resolution at 30Hz in both mirror and extend modes. Please note that this hub is compatible with MacBook (macOS 12 and newer), Windows 10 and 11, ChromeOS, and laptops equipped with DP Alt Mode and Power Delivery. Note: This device is not compatible with Linux.
- What You Get: Anker USB-C Hub (5-in-1, 4K HDMI), welcome guide, 18-month warranty, and our friendly customer service.
This is a practical fit when the question is whether project dependencies bring security or license issues into a JavaScript project. Sandworm describes itself as free and open source; check its site for current usage and licensing details relevant to your project.
4. Clair: Best For JavaScript In Container Images
Clair performs continuous static analysis of container images to find vulnerabilities and security problems in their contents. Its supported content includes JavaScript, alongside other languages, and it can be used in smaller environments such as a laptop or CI pipeline as well as with container registries.
Rank #3

Consider Clair when you need to assess JavaScript libraries as part of a container image. Its documented focus is container contents; the available information does not establish that it analyzes standalone JavaScript source files. Clair uses the Apache 2.0 license.
5. CodeChecker: Best For Managing JavaScript Analysis Reports
CodeChecker is static analysis infrastructure with web-based report storage. It can store and visualize thousands of reports from analyzers, including JavaScript analysis. That makes it relevant when your main need is a place to retain and inspect analysis results rather than a standalone JavaScript checker.
