5. 闭包-案例

闭包-案例：

1. 求平方
   Math.pow(6,2), 6的平方

function makePower(power) {
  return function(number) {
    return Math.pow(number, power)
  }
}
const pow = makePower(2)
console.log('pow', pow(6))
const pows = makePower(3)
console.log('pows', pows(2))

2. 计算基本工资 + 绩效工资
   getSalary(12000, 2000), getSalary(基本工资, 绩效工资)

function makeSalary(base) {
  return function(performance) {
    // 基本工资 + 绩效工资
    return base + performance
  }
}
const salaryLevel1 = makeSalary(12000)
const salaryLevel2 = makeSalary(16000)
console.log('salaryLevel1', salaryLevel1(2000))
console.log('salaryLevel2', salaryLevel2(6000))
