实现一个const

function myConst(obj, key, val) {
    Object.defineProperty(obj, key, { 
          value: val,
          writable: false,
         configurable: false
})
}

improve version

function myConst( key, val) {
    Object.defineProperty(window, key, { 
          value: val,
          writable: false,
         configurable: false
})
}

freeze

// 单层引用
const a = { name: 'dylan'}
const b = Object.assign({}, a)
const c = b
Object.freeze(b)
a.name = 'zeng'
c.age = 1
console.log(a, c)

second

// 单层引用
const a = { name: 'dylan'}
const b = Object.assign(a, {})
const c = b
Object.freeze(b)
a.name = 'zeng'
c.age = 1
console.log(a, c)

输出代码是否符合你的预期

let i = 0
function loading() {
    const url = pre + dot.repeat( i % 5 + 1)
    window.history.pushState(i, `loading`, url)
    i ++
}
setInterval(loading, 1000)
