Array of hashtags used

I'm trying to complete this exercise, returning an array with the hashtags used, but I'm only able to return "#" instead of the whole str[i]. What am I doing wrong?

This is my code so far: 

function extractHashtags(str) {

  let solution = [];
  for(let i=0; i<str.length; i++){
    if(str[i].startsWith('#')){
      solution.push(str[i]);
    }
  }
return solution;
}

    AssertionError: expected [ '#' ] to deeply equal [ '#yolo' ]
          + expected - actual

           [
          -  "#"
          +  "#yolo"
           ]

Trying to find out how to do it, came across this and I've also tried it this way:

function extractHashtags(str) {

  let solution = []; 
  solution.push(str.match(/[^#]/g));
  return solution;
}

But still doesn't work. I suppose the most elegant way is using regex, but I'm more than lost with it. Anyone can give me a hand? Thanks for your help!

See

solution.push(str[i]);

You're only pushing the initial '#' character - you want to push the whole word. Assuming tags are separated by spaces, you can try something like this instead:

const solution = str.split(' ').filter(word => word.startsWith('#'));
