str.split([separator[, limit]])

let sentence = "Hello World! How are you?";
let words = sentence.split(" "); // words: ["Hello", "World!", "How", "are", "you?"]

arr.push(element1[, ...[, elementN]])

let fruits = ["apple", "banana"];
fruits.push("orange", "grape"); // fruits: ["apple", "banana", "orange", "grape"]

let sentence = "One two three four five";
let numbersArray = [];
let wordsArray = sentence.split(" "); // wordsArray: ["One", "two", "three", "four", "five"]

wordsArray.forEach(word => {
  if (!isNaN(word)) { // 检查是否为数字字符串
    numbersArray.push(parseInt(word)); // 将数字字符串转换为整数并添加到numbersArray
  }
});

console.log(numbersArray); // 输出: [1, 2, 3, 4, 5]
