How to implement something like PHP's http_build_query and the reverse in javascript?

Question

\'bar\',
              \'baz\'=>\'boom\',
              \'cow\'=>\'milk\',
              \'php\'=>\'hypertext processor\');

You can use the URLSearchParams class:

var searchParametersData = {
  "foo": "baz",
  "bar": "foo"
};

var searchParameters = new URLSearchParams();

Object.keys(searchParametersData).forEach(function(parameterName) {
  searchParameters.append(parameterName, searchParametersData[parameterName]);
});

console.log(searchParameters.toString()); // foo=baz&bar=foo

To get the parameters object from a search parameter string, use this:

var searchParametersString = "foo=baz&bar=foo";

var searchParameters = new URLSearchParams(searchParametersString);

var searchParametersData = {};

for (var searchParameter of searchParameters) {
  searchParametersData[searchParameter[0]] = searchParameter[1];
}

console.log(searchParametersData); // {foo: "baz", bar: "foo"}
