Arrow function restore

var materials = [
  'Hydrogen',
  'Helium',
  'Lithium',
  'Beryllium'
];

console.log(materials.map(material => material.length));

寫出這個的標準函數形式，就像下面這個形式同樣
var selected = allJobs.filter(function (job) {
return job.isSelected();
};

var selected = allJobs.filter(job => job.isSelected());

 

標準函數形式：

var materials = [
  'Hydrogen',
  'Helium',
  'Lithium',
  'Beryllium'
];

console.log(materials.map(function(materils){                     return materils.length() })
