假設我們要檢查是否speech包含特定句子 ( reference)但在它的最后和結尾：這是reference：let reference = "have you ever look at someone";基于此，reference我們要比較speech并返回匹配或不匹配：let speech = "blaaaah have you ever look at someone"; // Match because 'have you ever look at someone' is at the end of speechlet speech = "have you ever look at someone blaaaah"; // No match because something else came after 'have you ever look at someone'問題是我無法區分上述語音示例并且代碼總是返回匹配：//let speech = "blaaaah have you ever look at someone"; // matchedlet speech = "have you ever look at someone blaaaah"; // No match let reference = "have you ever look at someone";if(new RegExp("\\b"+reference+"\\b").test(speech)){  console.log("Finally Matched!")} else {  console.log("No Match At Last!")}
