query-fetch.js

// import queryString from 'query-string'


const queryParams = queryString.parse(props.location.search);
        let selectCourse , selectService  ,  msgValue;
        selectCourse =  selectService  = false;

        if(queryParams['course'] !== undefined){
            selectCourse = true;
        }
        else if(queryParams['service'] !== undefined){
            selectService = true;
        }

        if(selectCourse)
            msgValue = `Hello! i would like to get enrolled in ${queryParams['course']} course, please register me, and send all the details through an email`
        else if(selectService)
            msgValue = `Hello! i would like to get ${queryParams['service']} service from you, please provide me what packages do you have for this service`
        else 
            msgValue= null;
