The output I expect for test.match(/[a-z]{0,}/g); should contain ”, ‘t’, ‘e’, ‘s’, ‘t’, ‘te’,

The output I expect for "test".match(/[a-z]{0,}/g); should contain '', 't', 'e', 's', 't', 'te', 'es', 'st', etc.

However I only get '' and 'test' from the console. What’s happening here?

    If what you are looking for is all word combinations, here is a code I’ve worked on:

    <html>
<body>

<script type="text/javascript">
function removeDuplicateElement(arrayName) {
    var newArray=new Array();
    label: for(var i=0; i<arrayName.length;i++){
        for(var j=0; j<newArray.length;j++) {
            if(newArray[j]==arrayName[i]) 
                continue label;
        }
        newArray[newArray.length] = arrayName[i];
    }
    return newArray;
}

var all=new Array();
var str="test";
for (;str.length>0;str=str.substring(1,str.length)) {
    for (var i = 0; i<=str.length;i++){
        var patt1=new RegExp("([a-z]{"+i+","+i+"})", "g");
        all=all.concat(str.match(patt1));
    }
}

document.write(removeDuplicateElement(all));
</script>

</body>
</html>

    For ‘test’, it returns ‘,t,e,s,te,st,tes,test,es,est’.
