Parse json files with comments? (keybindings.json) - vscode-extensions

Question

Does VSCode provides any means to parse json files with comments without using external library?
I'm trying get list of keybindings for the extension and need to parse keybindings.json file, which contains comments
I'm currently using JSON5 package, but would like to get rid of it:
//get keybindings
const keybindings = new Promise(resolve => {
//default keybindings
const data = require("../package.json").contributes.keybindings.reduce((a,b)=>(a[b.command]=b.key,a),{});
const parse = list => {
for(let i = 0; i < list.length; i++) {
if (list[i].command in data)
data[list[i].command] = list[i].key;
}
for(let i in data) {
//capitalize first letter
data[i] = data[i].replace(/\w+/g, w => (w.substring(0,1).toUpperCase()) + w.substring(1));
//add spaces around "+"
// data[i] = data[i].replace(/\+/g, " $& ");
}
Object.assign(keybindings, data);
resolve(data);
};
const path = {
windows: process.env.APPDATA + "/Code",
macos: process.env.HOME + "/Library/Application Support/Code",
linux: process.env.HOME + "/config/Code"
}[{
aix: "linux",
darwin: "macos",
freebsd: "linux",
linux: "linux",
openbsd: "linux",
sunos: "linux",
win32: "windows"
}[process.platform]||"windows"];
const file = ((process.env.VSCODE_PORTABLE ? process.env.VSCODE_PORTABLE + "/user-data/User/" : path) + "/User/keybindings.json")
.replace(/\//g, process.platform == "win32" ? "\\" : "/");
//read file
workspace.openTextDocument(file).then(doc => {
//we can't use JSON.parse() because file may contain comments
const JSON5 = require("json5").default;
parse(JSON5.parse(doc.getText()));
}).catch(er => {
parse([]);
});
});
