检查整个和精确的单词匹配

Question

我想要一个代码来检查整个和精确的单词匹配:)所以在我的逻辑中look不匹配looked。let speech = "you ever looked at someone";let a = "look";if(speech.includes(a)){  console.log("Whole Word Matches")} else {  console.log("No Match!")}如何修改上面的代码以检查整个单词匹配

Answer 1

if(new RegExp("\\b"+a+"\b").test(speech)){

 console.log("Whole Word Matches")

} else {

  console.log("No Match!")

}

Answer 2

您可以使用正则表达式(\bregExp\b)来查找单词的完全匹配项。

The \b metacharacter is used to find a match at the beginning or end of a word.

let speech = "you ever looked at someone";

let a = "look";

if(new RegExp("\\b"+a+"\\b").test(speech)){

  console.log("Whole Word Matches")

} else {

  console.log("No Match!")

}
