I wanted to know how to go through a Array and return the value of it.

In this case, it would be to compare if a word typed in a input has already been inserted before by another input and, if it was, it would have to be removed.

var palavras = ["mateus", "veloso", "vermelho"];

    if(palavras.includes(valor)){
      alert('palavra encontrada no array');
    }else{
      alert('palavra não encontrada no array');
    }
  });
});
