I can detect new instance made via Array() or new Array(). But what about []?
const originalArray = Array;
Array = new Proxy(Array,{
construct(target, args) {
console.log('new array');
const newArray = Reflect.construct(originalArray, args);
return newArray;
},
apply(target,thisArg,argArray){
console.log('apply');
Reflect.apply(target,thisArg,argArray);
}
});
var a = [3,2];// no handler
var b = Array(3,2);// apply
var c = new Array(3,2);// new
It is not possible to intercept object creation from literal syntax.
In fact, this was possible earlier due to a bug, which caused information leaks by making JSON vulnerable to hijacking .
