我怎麼能擺脫把「新」功能

Question

我不知道我怎樣才能使它更多鈔票來擺脫把「新」功能之前的之前，例如：

new functionToDo("thingsToDo").iGotYouBruh("Halo Humans"); 

是有沒有「新」這樣做的可行方法？

這裏是我想不「新」，使用代碼：

function local (title) { 
    var storeTitle = title; 
    this.addL = function(lString) { 
     var storeText = lString; 
     localStorage.setItem(storeTitle, storeText); 
     console.info("Locally stored " + storeTitle.toUpperCase() + " with " + storeText.substring(0, 10) + "... As text."); 
    }; 
    this.removeL = function() { 
     localStorage.removeItem(storeTitle); 
     console.info("Locally removed " + storeTitle + "."); 
    }; 
    this.getL = function() { 
     localStorage.getItem(storeTitle); 
     console.info("Locally got string of " + storeTitle + ": " + localStorage.getItem(storeTitle)); 
    }; 
}; 

和這裏就是我會做調用該函數：

new local("storedElement").getL();

這是可能的通過檢查this是否是該函數本身的一個實例，否則返回一個新實例：

function local (title) { 
    if (!(this instanceof local)) { 
     return new local(title); 
    } 

    var storeTitle = title; 
    this.addL = function(lString) { 
     var storeText = lString; 
     localStorage.setItem(storeTitle, storeText); 
     console.info("Locally stored " + storeTitle.toUpperCase() + " with " + storeText.substring(0, 10) + "... As text."); 
    }; 
    this.removeL = function() { 
     localStorage.removeItem(storeTitle); 
     console.info("Locally removed " + storeTitle + "."); 
    }; 
    this.getL = function() { 
     localStorage.getItem(storeTitle); 
     console.info("Locally got string of " + storeTitle + ": " + localStorage.getItem(storeTitle)); 
    }; 
};

您可以使用JavaScript關閉。尤其要看this webpage的「使用模塊模式的閉鎖」部分的完整說明。這個想法是讓函數返回一個包含所有必需方法的文字。任何你想保密的函數或變量都只是函數的局部變量。
