A JavaScript function to obtain GET parameters from a URL

GetURLParameters.js

//nodejs v4.2.6

'use strict'; // needed in nodejs v4.2.6 to enable "let" keyword

function GetURLParameters(url) { // url to provide as string
    let parameters_string = url.split("?")[1]; // all parameters comes after "?"
    let parameters = parameters_string.split("&"); // split to pairs of key/value
    let parameters_object = {}; // the object which will contain those pairs
    
    for (let i = 0; i < parameters.length; i++) {
        let key = parameters[i].split("=")[0]; // get the key
        let value = parameters[i].split("=")[1]; // get the value
        
        parameters_object[key] = value; // store the pair
    }
    
    parameters_object = JSON.stringify(parameters_object); // convert the parameters object into a JSON string
    
    return parameters_object;
}

console.log(GetURLParameters("https://www.example.com/index.php?key1=value1&key2=value2")); // returns '{"key1":"value1","key2":"value2"}'
