Some useful custom utility functions for cookie handling in javascript

// setCookie("cookiename", cookieExist, COOKIE_EXPIRY_TIME);// example - setCookie("username", cookieExist, (0.5 * 60 * 1000)); this cookie expires in 30 seconds.// the cookie expiry time have to be in seconds so convert your time in seconds and after that pass it.export function setCookie(cname, cvalue, exdays) {    const d = new Date();    d.setTime(d.getTime() + exdays);    let expires = "expires=" + d.toGMTString();    document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";}

// get a cookie and Its valueexport function getCookie(cname) {    let name = cname + "=";    let decodedCookie = decodeURIComponent(document.cookie);    let ca = decodedCookie.split(';');    for (let i = 0; i < ca.length; i++) {        let c = ca[i];        while (c.charAt(0) == ' ') {            c = c.substring(1);        }        if (c.indexOf(name) == 0) {            return c.substring(name.length, c.length);        }    }    return "";}

// pass the name of the cookie as string which you want to check that if It exists or not.export function checkCookie(cookiename) {    let cookieExist = getCookie(cookiename);    if (cookieExist != "") {        return cookieExist;    }    return false;}
