Only replace first match with .replace-CodePudding

I have a function that looks at a string of content & array of documents and finds any matches, then the user can accept or reject that match (another function). When the user accepts this match, see acceptLink function below, then I would like it to replace the first match and not all matches.

Example Content: "The first time I went home was when I went to see my dog at home."

Example Array: {name: 'Home', link: 'https://www.home.com/'}

Expected output: "The first time I went < a href=https://www.home.com/>Home< / a > was when I went to see my dog at home."

const acceptLink = (a) => {
      var reg = new RegExp('(' a.name ')', 'gi');
      const aTag = '<a   href='   a.link   '>'   a.name   '</a>'
      setContent(content.replace(reg, aTag));
      const replaceContent = content.replace(reg,aTag)
      const filtered = allLinks.filter(obj => {
      return obj.name !== a.name;
  });

Have I missed something here?

Remove g

const acceptLink = (a) => {
      var reg = new RegExp('(' a.name ')', 'i');
      const aTag = '<a   href='   a.link   '>'   a.name   '</a>'
      setContent(content.replace(reg, aTag));
      const replaceContent = content.replace(reg,aTag)
      const filtered = allLinks.filter(obj => {
      return obj.name !== a.name;
  });
