solution ✅

zero bug

let key = `ali`.toLocaleUpperCase();
// let name = "阿里云计算有限公司 alibaba";
let name = "AliOS"

const getHighlightOthers = (names = ``, type = `prefix`) => {
  let name = names;
    let result = ``;
    let prefix = 0;
    let suffix = 0;
    if (name && name.length) {
        if (type === `prefix`) {
            prefix = name.toLocaleUpperCase().indexOf(key);
            if(prefix >= 0) {
                result = name.substr(0, prefix);
            }
        } else {
            suffix = name.toLocaleUpperCase().indexOf(key);
            if(suffix >= 0) {
               result = name.substr(suffix  + key.length);
             } else {
                    result = name;
                }
        }
    }
    console.log(`result =`, result, type);
    return result;
};
const getHighlightKeyword = (name = ``) => {
    // null
    let result = ``;
    let prefix = 0;
    if (name && name.length) {
        prefix = name.toLocaleUpperCase().indexOf(key);
