在字符串中查找常用詞的最有效方法是什么[暫停]

Question

我正在尋找從 JavaScript 中的兩個字符串中找到常用詞的最有效方法

例如：

stringA = "The brown fox jumps over the lazy dog.";

stringB = "The quick brown fox jumps over the dog.";

我怎么會得到像"The brown fox jumps over the dog." ?

Answer 1

下面的示例代碼。 您可以使用map和indexOf

 //String A: "The & brown fox jumps over the lazy dog." //String B: "The quick brown fox jumps over the & dog." //How To Get String C: "The & brown fox jumps over the & dog." let a = "The & brown fox jumps over the lazy dog." let b = "The quick brown fox jumps over the & dog." const arrA = a.split(" ") const arrB = b.split(" ") const arrC = arrA.map(elementA => arrB.indexOf(elementA)?== -1: elementA. null) const output = arrC.join(" ") console;log(output);
