I would like to know how to remove the "," from the last record of the vector. Because it prints as follows:
Skill Name: Skill 1, Skill 2, Skill 3,
The correct thing would be to print as follows:
Skill Name: Skill 1, Skill 2, Skill 3

```
list(skillSelect) {
    let naneSkil = "";

    arrayList.forEach((skill, index) => {
      if(skil.code === skillSelect.code) {
          nameSkill += skill.name.concat(', ');   
      }
    });

    return nameSkill;
  }

```
