先看提速效果

上图：使用默认设置（包括缩小和源映射）从头开始制作包含 10 个three.js库副本的生产包的时间。更多信息在。
我们当前用于 Web 的构建工具比esbuild速度可能慢 10-100 倍。 项目的主要目标是开创一个构建工具性能的新时代，并在此过程中创建一个易于使用的现代 bundler。

来个demo

const res = add(1,2);

const res2 = uuidv4();
const time =  moment().format(‘MMMM Do YYYY, h:mm:ss a‘); 
console.log(res, res1, res2, time);
console.log(chalk.blue(‘Hello world!‘));

看看实际效果

而且webpack编译 还会随着项目体积的增大而编译耗时直线上升
