JavaScript 中字符与字符串重叠

积累知识，胜过积蓄金银！毕竟在文章开发的过程中，会遇到各种各样的问题，往往都是一些细节知识点还没有掌握好而导致的，因此基础知识点的积累是很重要的。下面本文《JavaScript 中字符与字符串重叠》，就带大家讲解一下知识点，若是你对本文感兴趣，或者是想搞懂其中某个知识点，就请你继续往下看吧~

编写一个函数，它接受两个字符串并显示出现在任一字符串中的字符（不带双精度）。

解决方案

function characteroverlap(array1, array2) {
  let occurrence = {};

  let str = array1.concat(array2);

  // find the count of each character
  array.from(str).foreach((char) => {
    let currentcount = occurrence[char] || 0;
    occurrence[char] = currentcount + 1;
  });

  // return the keys which is the individual character and join.
  const result = object.keys(occurrence);

  return result.join("");
}

console.log(characteroverlap("computer", "circuitemtop"));
console.log(characteroverlap("frontend", "development"));
console.log(characteroverlap("mivrog", "gormiv"));
console.log(characteroverlap("praxet", "xetpar"));
console.log(characteroverlap("stone", "tones"));
console.log(characteroverlap("rescue", "secure"));

结果

> computer
> frontedvlpm
> mivrog
> praxet
> stone
> rescu
