java_js_避免无意义的条件判断

 1 反例:
 2 function createMicrobrewery(name) {
 3   var breweryName;
 4   if (name) {
 5     breweryName = name;
 6   } else {
 7     breweryName = 'Hipster Brew Co.';
 8   }
 9 }
10 正例:
11 
12 function createMicrobrewery(name) {
13   var breweryName = name || 'Hipster Brew Co.'
14 }
