Question

I have a statement:

var sep = '  |  ';
var r = '';
for (var i = 0; i < menuItems.length; i++) {
    r += function(menuObject) {
    console.log(menuObject);
    console.log(
        '<a class="" href="' + 
        menuObject.url + '">' + menuObject.name + '</a>' + 
        (i < menuItems.length - 1) ? sep : ""); //logs the contents of sep
    ) //console.log expanded for readability
    }
}

Why is it not logging the full string, and instead only evaluating to sep?

Answer 1

Because you are not wrapping your if line in parenthesis and it is process all of the string before it as the condition.

Try this…

var sep = '  |  ';
        var r = '';
        for (var i=0;i<menuItems.length; i++) {
            r += function (menuObject) {
            console.log(menuObject);
            console.log(
                '<a class="" href="' + 
                menuObject.url + '">' + menuObject.name + '</a>'+ 
                ((i <menuItems.length-1 ) ? sep : "")); //logs the contents of sep
            }
       }
