在字符串中查找常用词的最有效方法是什么[暂停]

Question

I am looking for the most efficient way to find the common words from two Strings in JavaScript

for example:

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

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

How would I get something like "The brown fox jumps over the dog." ?

Sample code below. You can use map and 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);
