有没有什么语法可以缩短这段代码？

if (condition) {
    result = value1;
} else {
    result = value2;
}

result = condition ? value1 : value2;

function add(a, b) {
    return a + b;
}

const add = (a, b) => a + b;

const user = {
    name: 'John',
    age: 30,
    gender: 'male'
};
const name = user.name;
const age = user.age;

const { name, age } = user;

const name = 'John';
const message = 'Hello, ' + name + '!';

const name = 'John';
const message = `Hello, ${name}!`;
