Javascript Solves Cryptocurrency Equations

The following solves either x A = ? B or ? A = x B.

let a = pair[0].trim().toUpperCase();
let b = pair[1].trim().toUpperCase();
let c = pair[2].trim().toUpperCase();
// e.g. 100 BTC SBD
if (isNumeric(a) && isValidSymbol(b) && isValidSymbol(c)) {
    let dom = $('div#conversion_results');
    let dom_id = "cc_" + removeInvalid(a) + "_" + removeInvalid(b) + "_" + removeInvalid(c);
    dom.append('<div id="' + dom_id + '"> </div>');
    getConversion(b, c).then(x => {
        $('div#' + dom_id).html("<h4>" + a + " " + b.toUpperCase() + " = <span class=yellow>" + (x * a) + "</span> " + c.toUpperCase() + "</h4>");
    });
