i wish i could see the test code because it works for the beginning test

intresting thank you

For example the input is 98. Then it will return the string for '90'

var re = /\b\w[e, é, i, í, ö, ő, ü, ű]\w/;
var na = /[\w[a, á, o, ó, u, ú]\w]$/;

is something wrong with my regex new to this
I have an if statement after but it is only returning nek

thxs

what does this line of code mean
[...arr1, ...arr2];

I get the reduce method.

Nice
