如何在没有foreach()的情况下使用string.split()？

let str = "apple,banana,cherry";
let parts = str.split(',');

for (let i = 0; i < parts.length; i++) {
    console.log(parts[i]);
}

let str = "apple,banana,cherry";
let parts = str.split(',');

let result = parts.map(function(item) {
    return item.toUpperCase();
});

console.log(result); // 输出: ["APPLE", "BANANA", "CHERRY"]

let str = "apple,banana,cherry";
let parts = str.split(',');

let concatenated = parts.reduce(function(accumulator, currentValue) {
    return accumulator + currentValue;
}, '');

console.log(concatenated); // 输出: "applebanana"

let str = "apple,banana,cherry";
let parts = str.split(',');

let filtered = parts.filter(function(item) {
    return item.length > 5;
});

console.log(filtered); // 输出: ["banana"]

let str = "apple,banana,cherry";
let parts = str.split(',');

let hasLongWord = parts.some(function(item) {
    return item.length > 5;
});

console.log(hasLongWord); // 输出: true

let allShortWords = parts.every(function(item) {
    return item.length <= 5;
});

console.log(allShortWords); // 输出: false

let str = "apple,banana,cherry";
let parts = str.split(',');

Array.from(parts, item => console.log(item.toUpperCase()));
