A more modern version, using newer APIs:

/**
 * queryStringToDict
 * @example `queryStringToDict("foo=bar&baz=abc")` will return `{ foo: "bar", baz: "abc" }`
 * @param {string} queryString a query string, e.g. "foo=bar&baz=abc" (a leading `?` is optional)
 * @returns {Record<string, string>}
 * 
const queryStringToDict = queryString => Object.fromEntries(new URLSearchParams(queryString))
