用于 TypeScript 语法的 Suar Syntax

const person = {
  id: 'abx',
  ...(isVliad && { isActive: true }),
  ...((age >= 10 || isValid) && { card: true }),
}

const person = { id: 'abc' }
console.log('id' in person)

const productData = { id: '12', name: 'laptop' }
const { id: helloworld } = productData
console.log(helloworld, 'hello world is')

const data = {id:1, name: 'laptop', isSale:true}
Object.entries(data).forEach(([key,value])=>{
  console.log(`${key} and ${value}`)
})

const data = {id:1, name: 'laptop', isSale:true}
console.log(data?.id)
console.log(data?.hello)
data?.nameDiplay?.()

const fruitList = ['apple', null , 'mango']
const filteredFruit = fruitList.filter(Boolean)
const isANyFruit = fruitList.some(Boolean)

const fruitList = ['apple', 'mango', 'apple']
const uniqFruit = [...new Set(fruitList)]
