I am on the 5/15 lessons on Learn Node.js:
I completed Instruction 1: module.exports = class Cat
but the check box didn’t change, and the rest of the instructions remained grey. I checked the hint and saw that my line was correct. Since I could still read the greyed out instructions, I continued to Instruction 2: module.exports = class Dog (compared it with the hint)
And in Instruction 3 wrote the two require():
// Require modules in:
let Dog = require(’./dog.js’);
let Cat = require(’./cat.js’);
Then I called node app.js and received a result for the “dog-cat fight”.
I did this page several times, refreshed it, and got “Rex wins!”, and then “Taby wins!” and no error message:
node app.js Tabby wins!
But no change and the Next button remains stuck.
