TSLint: Shadowed name in map. Is this false positive?

Question

I have the following TypeScript / Javascript codes for producing multiple line using jQuery.

let evenLine = false;
   const divs = clientsInfo.map((m) => {
      const div = $('<li/>', { class: 'hubClientInfo' + (evenLine ? ' even' : ' odd') });
      evenLine = !evenLine;

      div.append($('<span/>', { class: 'hc-userAgent' }).text(m.userAgent));
      div.append($('<span/>', { class: 'hc-ip' }).text(m.ipAddress));
      div.append($('<span/>', { class: 'time' }).text(m.connectedTimeUtc.toString()));

      div.append($('<span/>', { class: 'hc-user' }).text(m.username));
      div.append($('<span/>', { class: 'hc-id' }).text(m.id));

      return div;
});

TSLint reports Shadowed name regarding to "evenLine".

Is this a false alarm? or is there a way to improve the codes to avoid such alarm?

Answer 1

Eventually I had found that down the bottom of the TS file there's a "evenLine" declared globally outside any class or module. So renaming those "evenLine" within a function scope had fixed the TSLint warning, while the program has been working properly.
