程式語言熱門度排名
TIOBE Index 是全球公認客觀的程式語言熱門度指標，一個月會更新一次。要注意的是這個排名只是單純的熱門度，不代表程式語言的好壞或是用該程式語言寫出來的程式碼行數多寡。
如何評分？
排名是依據該語言在全世界工程師、課程、以及第三方廠商所使用的數量來評比其熱門度。而這些數字也依靠著許多知名的搜尋引擎 Google, MSN, Yahoo!, Wikipedia and Youtube 來協助計算。
TIOBE 眼中，怎麼樣才算是個程式語言？
- 至少在有個維基百科的頁面。
- 語言本身必須是 Turing-Complete。舉例來說：SQL 因為無法撰寫無窮迴圈，所以不算。
重點來了，截至今日，最熱門的語言是什麼？

可以發現雖然 Java 與 C++ 各自佔據第一、三名，但是長期看來熱門度是持續下滑的。
許多專家都不太看好 Java 的未來，目前看起來應該是因為 Android 而持續苦撐。
讓我們持續關注下去吧！
