no need to set any meta tag neither the csrf_token() nor the csrf_field() !

You could use this jQuery snippet :

$.ajaxPrefilter(function( settings, original, xhr ) {
    if (['post','put','delete'].includes(settings.type.toLowerCase())
        && !settings.crossDomain) {
            xhr.setRequestHeader("X-XSRF-TOKEN", getCookie('XSRF-TOKEN'));
    }
});

function getCookie(name) {
    var cookieValue = null;
    if (document.cookie && document.cookie != '') {
        var cookies = document.cookie.split(';');
        for (var i = 0; i < cookies.length; i++) {
            var cookie = jQuery.trim(cookies[i]);
            // Does this cookie string begin with the name we want?
            if (cookie.substring(0, name.length + 1) == (name + '=')) {
                cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                break;
            }
        }
    }
    return cookieValue;
}

just few other answers tried to set the csrf header but according the Laravel documents (here) , the header key should be "X-XSRF-TOKEN" and Laravel itself provides the needed value on every request for us in a cookie named "XSRF-TOKEN"

so just corrected the keys and edited few lines,thanks
