JavaScript查找一个数组中符合某个条件的值，并将符合条件的值存入新的数组

var newArray  = {};//新对象
var array = [
 {name:'aiai',age:18},
 {name:'sisi',age:18},
 {name:'lulu',age:18},
 {name:'sisi',age:19}
]; 
//查找符合条件值并存入新数组
newArrar = this.array.find((item) => {
   if(item.name === 'sisi'){
     return item
   }
 })
//此时 newArray = {name:'sisi',age:18}
