ECMASCRIPT中的反引号：意外的令牌非法

Question

I am writing a small test code in an ExpressJs app. The code is as follows :

var express = require('express');
var app = express();
var dataFile = require('./data/data.json');


app.set('port', process.env.PORT || 3000);

app.get('/', function(req, res) {
  var info = '';
  dataFile.speakers.forEach(function(item) {
    info += `<li>
      <h2>${item.name}</h2>
      <p>${item.summary}</p>
    </li>
    `;
  });
  res.send(`
    <h1>My Meetups</h1>
    ${info}
    `);
});

var server = app.listen(app.get('port'), function() {
  console.log('Listening on port ' + app.get('port'));
});

When I try to execute the command

node app/app.js

in Git bash terminal, I get the following error :

> E:\expressjs\app\app.js:11
>     info += `<li>
>             ^ SyntaxError: Unexpected token ILLEGAL
>     at Module._compile (module.js:439:25)

>     at Function.Module.runMain (module.js:497:10)
>     at startup (node.js:119:16)
>     at node.js:935:3

What I tried :

1. Checked node version : Using node 0.10.37
2. Tried running the node command with --harmony option as suggested : Same error
3. Tried visiting the ECMA compatibility table website : Wasn't able to search the right information

Am using the Atom Editor

What I suspect : Incompatible version of Node and ECMA

Can someone help with this ?

Thanks

Try this site. It shows all es6 features implemented in nodeJS

http://node.green/

My suspect is that you using very old version of node(almost all features gives error in node 0.10).

Try to upgrade into node6 and all should be OK.

Hope this helps.
