本篇文章屬個人見解，若有錯誤部分，請不吝指教

版本：ECMAScript 2015/ES6

說明

簡單來說，Number.parseFloat()跟parseFloat()就是一樣的功能，而為什麼在ES2015之後，會出現一樣的Function呢，這是為了模組化。所以未來也許parseFloat會被移除也說不定呢。

MDN裡Number.parseFloat的說明

This method has the same functionality as the global parseFloat() function:
Number.parseFloat === parseFloat; // true
This method is also part of ECMAScript 2015. (Its purpose is modularization of globals.)
