Answer / Ruchi
To extract a query string from a URL using Regular Expressions in JavaScript, you can use the following example:nn```javascriptnfunction getQueryString(url) {n const regex = new RegExp('(?:?|&)([^=#]*)=([^&#]*)');n const results = url.matchAll(regex);n let params = {};n for (const result of results) {n params[decodeURIComponent(result[1])] = decodeURIComponent(result[2]);n }n return params;n}n```
