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
