initialize the newVal array with map so that it has one more attribute b than the value array, but there is no response on the view when the b attribute is changed. You can change the following code in the watch method to take effect
const arr = newVal.map(item => {
item.b = true;
return item;
})
this.newVal = JSON.parse(JSON.stringify(arr))but didn"t array.prototype.map generate a new array? why didn"t the b attribute add watch
