debounce(callback, time)

• Function for avoiding shake
• example:

 test('test true', () => {
    const debounce = adam.debounce
    jest.useFakeTimers() // 声明语句，启用jest伪装计时器函数，因为使用了advanceTimersByTime()
    const callback = jest.fn() // 声明语句，使用jest伪装函数
    const createDebounce = debounce(callback, 300)
    expect(callback).not.toBeCalled() // callback还未被调用
    for (let i = 0; i < 11; i++) { // 循环执行createDebounce 11次，每次都在经过299ms时setTimeout被刷新
      createDebounce()
      jest.advanceTimersByTime(299) // 过了299ms
    }
    expect(callback).not.toBeCalled() // callback还未被调用
    jest.advanceTimersByTime(1) // 再过1ms
    expect(callback).toBeCalled() // callback被调用
    expect(callback).toHaveBeenCalledTimes(1) // callback只被调用1次
  })

removeItemByIndex(index, arr)

• Function for remove item by index

adam.removeItemByIndex(1, [1, 2, 3]) //return [1, 3]

stack.push(el)              // 向该栈内压入一个 el 数据
const s = stack.pop()       // 该栈弹出栈顶元素并返回(会在该栈中删除该元素)
const top = stack.peek()    // 查询该栈的栈顶元素，并返回栈顶元素(不会在该栈中删除该元素)
const tf = stack.isEmpty()  // 判断该栈是否是一个空栈，返回 true | false
stack.clear()               // 清空该栈
const len = stack.length()  // 返回该栈的长度，返回一个数字

isPalindrome(word)

• Function for 判断是否是一个回文
• 区分大小写

adam.isPalindrome('hello') // false
adam.isPalindrome('racecar') // true

mulBase(num, base)

• Function for 进行数值转换
• num 为需要转换的数
• base 为转换为几进制

adam.mulBase(4, 2) // 100
adam.mulBase(8, 2) // 1000
