Best solution to find out if a number is even.

Where does the data come from? Where does it go? Why isn't this an endless recursive loop? Why has this worked for three years?

Found this in a project at work and someone clearly doesn't trust JavaScripts typeof function
var div = '<div class="imgdiv" '+(user[5] ? 'style="display: flex; flex-direction: column; padding: 10px; justify-content: flex-end; background-image: url(\''+user[5]+'\');"' : '')+'>'

+ (iam && page=='home' ? '<div> <input id="video-input" onchange="uploadVideo(files)" type="file" accept="video/*" style="display: none; width: 80%; height: 100px; margin: auto; padding-top: 20px;"/> </div> <p class="action_cont" style="padding: 0; padding-top: 12;"> <a class="act_btn" onmousedown=document.getElementById("video-input").click() href="javascript:void(0)" style="text-decoration: none; margin: auto; width: calc(100% - 26px); text-align: center;"> ' + (myMods['video'] ?

var ValidChars = "0123456789.";
var IsNumber = true;
var Char;

Char = sText.charAt(i);
if (ValidChars.indexOf(Char) == -1) {

So I suppose that "........" is a valid number...
