Javascript替换了字符串的某些部分

// 简单替换
let str = "Hello World!";
let newStr = str.replace("World", "Universe");
console.log(newStr); // 输出: Hello Universe!

// 全局替换
str = "apple, apple pie, apple juice";
newStr = str.replace(/apple/g, "orange");
console.log(newStr); // 输出: orange, orange pie, orange juice

// 忽略大小写替换
str = "JavaScript is Great";
newStr = str.replace(/great/i, "awesome");
console.log(newStr); // 输出: JavaScript is Awesome

let str = "apple, apple pie, apple juice";
let newStr = str.replace(/apple/g, "orange");
console.log(newStr); // 输出: orange, orange pie, orange juice

let str = "JavaScript is Great";
let newStr = str.replace(/great/i, "awesome");
console.log(newStr); // 输出: JavaScript is Awesome
