如何将字符串与字符串数组匹配

// 精确匹配
function exactMatch(arr, str) {
    return arr.filter(item => item === str);
}

// 部分匹配
function partialMatch(arr, str) {
    return arr.filter(item => item.includes(str));
}

// 通配符匹配
function wildcardMatch(arr, pattern) {
    const regex = new RegExp(pattern.replace(/\*/g, '.*').replace(/\?/g, '.'));
    return arr.filter(item => regex.test(item));
}

// 正则表达式匹配
function regexMatch(arr, regexPattern) {
    const regex = new RegExp(regexPattern);
    return arr.filter(item => regex.test(item));
}

// 示例数组
const array = ["apple", "banana", "apricot", "grape", "orange"];

console.log(exactMatch(array, "apple")); // 输出: ["apple"]
console.log(partialMatch(array, "ap")); // 输出: ["apple", "apricot"]
console.log(wildcardMatch(array, "a*")); // 输出: ["apple", "apricot"]
console.log(regexMatch(array, "^a")); // 输出: ["apple", "apricot"]
