最近在用eslint代碼檢測，因為之前不太注意代碼規范，剛開始確實頭疼，哈哈，不過用習慣了就會感覺還不錯，其實也沒有那樣難調試

針對自己項目中遇到的一些提示，做一些舉例說明：
1 [W099]：Mixed spaces and tabs
這個錯誤是最常見的，意思是在同一行中，空格和Tab縮進混合使用了，修改很簡單，一般是刪除Tab縮進，全部改為空格。為了方便，我們可以把編輯器的Tab縮進設置成2個或4個空格，來代替原有的縮進。
2 [W030]：Expected an assignment or function call and instead saw an expression
這個錯誤提示的很詭異，我是用如下代碼提示的這個錯誤 index-1 <0 ? index = 0:index = index - 1; 這是一個逗號表達式，但是JSLInt認為這里不應該用表達式，而必須是一個函數，所以，如果非常在乎這個錯誤，就改為if else 語句吧
3 [W041]：Use '===' to compare with ...
這個錯誤是說，我們要是用全等來代替等於，如果表達式兩邊的數據類型是一致的話，建議使用全等來判斷
4 [W033]：Missing semicolon
缺少分號；這個一般都是自己忘記寫了吧，但是有一個需要注意的是，對於只有一句的結構，后面也需要寫分號。例如：if(index<0) {index=tcount-1} 這句代碼，正確寫法是if(index<0) {index=tcount-1;}，我是經常忘記這里寫分號，汗...
其他還有一些錯誤提示就對照一下改吧，要培養自己良好的代碼風格和書寫習慣。
