var xhr = new XMLHttpRequest(); xhr.onreadystatechange = function (){ if (xhr.readyState === 4) { var employees = JSON.parse(xhr.responseText); var statusHTML = '<lu class="bulleted">'; for (var i = 0; i < employees.length; i =+ 1) { if (employees[i].inoffice === true){ statusHTML += '<li class="in">'; }else{ statusHTML += '<li class="out">'; } statusHTML += employees[i].name; //the error is here: Uncaught RangeError: Invalid string length statusHTML += '</li>'; } statusHTML += '</ul>'; document.getElementById('employeeList').innerHTML = statusHTML; } }; xhr.open('GET', 'data/employees.json'); xhr.send();

for (var i = 0; i < employees.length; i = +1) { // you probably want "i += 1" instead here

Full Stack JavaScript Techdegree Student 14,147 PointsSteven Parker is there anything in the console or ide that could help with an error say like non-terminating loop pending before execution?

231,172 PointsSomething like a "non-terminating loop" might not be what you intended, but it's not actually a program error from the viewpoint of the language itself.
I believe some IDE's have a facility to detect and interrupt a program that is looping very quickly, but I don't think the workspace does. But your browser may have debugging features that allow you to manually interrupt a program and to set breakpoints to occur when things (like too many iterations) occur.
