Regex to replace URL path params with values

parsePathParams.js

var path = '/network/{id}/device/{serial}';

params = {
id:"123456",
serial: "abcd-abcd-abcd"
}

var paramNames = Object.keys(params);
console.log('paramNames', paramNames);

var mapping = {};
paramNames.forEach((e,i) => mapping[`{${e}}`] = params[e]);
newPath = path.replace(/\{\w+\}/ig, n => mapping[n]);

console.log("path", path);
console.log('netPath', newPath);
