Add for(integerVal) counting loops #709

Closed JaneOri closed 4 years ago

JaneOri commented 5 years ago

Hey fam!

This adds integer count loops to output based on numbers. Most frequently for me I've needed this for heavy visual builds.

    var template = stache("<div>{{#for(integerValue)}}[{{scope.index}}]{{/for}}</div>");
    var frag = template({
        integerValue: 3
    });
    // frag.firstChild.innerHTML === "[0][1][2]"

I queried about this years ago, wish I would have taken a look sooner since it was so easy to implement.

I understand if you decide against the feature, but I'd really like to have it and would be happy to discuss further if needed!

Hope you're all well! //James
