Javascript to handle conversion

// conversion
const processConversion = (s) => {
    let arr = s.trim().split("\n");
    for (let i = 0; i < arr.length; i ++) {
        let pair = arr[i].split(" ");
        if (pair.length == 2) {
            let a = pair[0].trim().toLowerCase();
            let b = pair[1].trim().toLowerCase();
            var pat = /^[a-zA-Z\-]+$/;
            if (pat.test(a) && pat.test(b)) {
                let dom = $('div#conversion_results');
                let dom_id = "convert_" + removeInvalid(a) + "_" + removeInvalid(b);
                dom.append('<div id="' + dom_id + '"> </div>');
                getConversion(a, b).then(x => {
                    $('div#' + dom_id).html("<h4>1 " + a.toUpperCase() + " = <span class=yellow>" + x + "</span> " + b.toUpperCase() + "</h4>");
                });
            }
        } else if (pair.length == 1) {
            let a = pair[0].trim().toUpperCase();
            let currency = $('select#currency').val();
            var pat = /^[a-zA-Z\-]+$/;
            if (pat.test(a)) {
                if (a in coinmarkcap) {
                    a = coinmarkcap[a];                    
                }                
                let api = 'https://api.coinmarketcap.com/v1/ticker/' + a.toLowerCase() + '/';

                    $('textarea#convert_result').append(getCoinReport(result, currency));
                }).catch(function(error) {
                    logit('Request failed: ' + api + ": " + error);
