typeScript学习笔记

1、变量申明，展开运算符

let defaults = {
  food: 'spicy',
  price: '20',
  ambiance: 'noisy'
}

let search = {...defaults, food: 'rich'}

console.log(search)

{ food: 'rich', price: '20', ambiance: 'noisy' }

let defaults = {
  food: 'spicy',
  price: '20',
  ambiance: 'noisy'
}

let search = {food: 'rich', ...defaults}

console.log(search)

{ food: 'spicy', price: '20', ambiance: 'noisy' }

使用展开运算符的时候，注意顺序
