[javascript] Safely turning a JSON string into an object

I found a "better" way:

In CoffeeScript:

try data = JSON.parse(jqxhr.responseText)
data ||= { message: 'Server error, please retry' }

In Javascript:

var data;

try {
  data = JSON.parse(jqxhr.responseText);
} catch (_error) {}

data || (data = {
  message: 'Server error, please retry'
});
