Problem with test on the server.

I run code in the browther and in webstorm - work corect, but checking on server lead to error -"Your result:{}" Is somebody know what is go on? my code:

function popularWords(text: string, words: string[]) {
// your code here
let myMap:Map<string,number> = setmap(words);
for (let i = 0; i < words.length; i++) {
    let reg = new RegExp(\`\\b${words[i]}\\b\`,'ig');
   // console.log(reg)
    let res = text.match(reg);
    if(res!==null){
        myMap.set(words[i],res.length)
    }

}
return myMap;

}

function setmap(words: string[]) {
let map = new Map();
for (let i = 0; i < words.length; i++) {
    map.set(words[i], 0);
}
return map;

}

console.log(popularWords(`\nWhen I was One\nI had just begun\nWhen I was Two\nI was nearly new\n`,["i","was","three","near"]));
result === Map { 'i' => 4, 'was' => 3, 'three' => 0, 'near' => 0 }
