The run test function

All my exercises on coding lessons provided in the curriculum are not being marked or am not being given feedback of results after clicking the “run test button”. It keeps running the tests but no responses are coming. Is it a network issue? Because I used to get responses but they have since stopped and I cant track my progress.

please help!

// Example
var ourStr = "I come first. " + "I come second.";

// Only change code below this line

var myStr = "This is the start." + "This is the end.";

Your code is not enough to pass the challenge - you are missing a space in the middle of the string

The challenge tests do not work well on Safari, Edge, or Internet Explorer. The curriculum works best when using Chrome.
