I am trying to get the number of items in an array then run a function X times.

I am trying to get the number of items in an array then run a function that amount of times. Is this possible in JavaScript? I am storing the array in JSON.

This is the code I have set up for when there is only 1 app

if (localStorage.getItem("repo")) {
  repo = JSON.parse(localStorage.getItem("repo"));
  create_app(repo.app.appName, repo.app.appIcon, repo.app.appId, repo.app.appUrl);
};

This is what the JSON looks like. The array I am trying to access is called "apps".

{
    "repoName": "repo_name",
    "repoId": "unique_id",
    "repoVer": "1",
    "apps": [{
        "appName": "first app name"
        "appId": "app1",
        "appUrl": "https://example.com",
        "appIcon": "https://example.com/favicon.ico"
      },
    {
      "appName": "second app name",
      "appId": "app2",
      "appUrl": "https://example.org",
      "appIcon": "https://example.org/favicon.ico"
  }]
}
