this issue is not reproducible.

var helloWorld = function() {}

works fine for this kata

Good

Está bien pero podrias directamente cambiar el operador a negativo :D

I had the same solution but without the '+' and of course got a string returned. Had to google this unary plus and learned something really cool and valuable today thanks to you. Thanks!

Nice

I couldn't even think about get info().
Guess I have a long way to go.

What mattc said, plus I find it easier to mentally interpret a template string than a concatenated string.

Template Strings, Well the template strings get's evaluated to this.name + 's age is ' + this.age; anyway. The reason I used it was because this kata is about the new JS2015 standard which is where the Template Strings were introduced so I personally found them appropriate to use.

${this.name}s age is ${this.age};
What do you call this notation, and why use it over:
this.name + 's age is ' + this.age;

I believe many new rubyist will find this a good exercise to learn about indices, it was a nice refresher for me.

Please don't use coloured text. It might look okay on the default dark theme, but it's unreadable on the light theme.

you can do "var hw = function() {...}; var helloWorld = hw;"

Raised on the support system... I'll comment here when I get an update. You can get around it though ;)

Seems to be a weird codewars issue itself, let me see if I can work out who to raise it with!

If you do "var helloWorld = function() {}" it becomes "var helloWorld = function helloWorld()" when you run the tests... but I have no idea why.
