`manage_node_deps.py` was changed in https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/2259834 to add line endings at the end of the package.json file However, `npm run install-deps` was not rerun to add the line endings. To prevent future CLs that add deps to include the line ending changes, fix them in this CL.

Acorn-JSX
This is plugin for Acorn - a tiny, fast JavaScript parser, written completely in JavaScript.
It was created as an experimental alternative, faster React.js JSX parser. Later, it replaced the official parser and these days is used by many prominent development tools.
Transpiler
Please note that this tool only parses source code to JSX AST, which is useful for various language tools and services. If you want to transpile your code to regular ES5-compliant JavaScript with source map, check out Babel and Buble transpilers which use acorn-jsx under the hood.
Usage
Requiring this module provides you with an Acorn plugin that you can use like this:
var acorn = require("acorn");
var jsx = require("acorn-jsx");
acorn.Parser.extend(jsx()).parse("my(<jsx/>, 'code');");
Note that official spec doesn't support mix of XML namespaces and object-style access in tag names (#27) like in <namespace:Object.Property />, so it was deprecated in acorn-jsx@3.0. If you still want to opt-in to support of such constructions, you can pass the following option:
acorn.Parser.extend(jsx({ allowNamespacedObjects: true }))
Also, since most apps use pure React transformer, a new option was introduced that allows to prohibit namespaces completely:
acorn.Parser.extend(jsx({ allowNamespaces: false }))
Note that by default allowNamespaces is enabled for spec compliancy.
