7isJavaScript(h('script', {type: 'text/fooscript'})) //=> false
8isJavaScript(h('script', {language: 'fooscript'})) //=> false

API

`isJavaScript(node)`

Check if a node is a <script> that contains or references JavaScript.

Returns true if node is a <script> element that has a valid JavaScript type, has no type and a valid JavaScript language, or has neither.

Parameters

node (Node) — node to check

Returns

Whether a node is a <script> that contains or references JavaScript (boolean).

Syntax

HTML is parsed according to WHATWG HTML (the living standard), which is also followed by all browsers.

Syntax tree

The syntax tree used is hast.

Types

This package is fully typed with TypeScript.

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, hast-util-is-javascript@^3, compatible with Node.js 16.

Security

Determines if the project uses fuzzing.
