js時間YYYY-MM-DD轉換爲英文顯示

目標：將2019-1-2轉換成Jan 01, 2019
實現方式：

let date = new Date('2019-1-2'); //Wed Jan 02 2019 00:00:00 GMT+0800 (China Standard Time)

let chinaDate = date.toDateString(); //"Tue, 01 Jan 2019 16:00:00 GMT"
//注意：此處時間爲中國時區，如果是全球項目，需要轉成【協調世界時】（UTC）
let globalDate = date.toUTCString(); //"Wed Jan 02 2019"

//之後的處理是一樣的
let chinaDateArray = chinaDate.split(' '); //["Wed", "Jan", "02", "2019"]

let displayDate = `${chinaDateArray[1]} ${chinaDateArray[2]}, ${chinaDateArray[3]}`; //"Jan 02, 2019"
