Is there destructor in typeScript

问题

Is there destructor in TypeScript? If not, how can I delete an object? I tried destructor() and ~ClassName() but it didn't work.

回答1:

JavaScript uses garbage collection to automatically delete objects when they are no longer referenced. There is no concept of destructors or finalizers.

You can't observe when an object is deleted by the garbage collector, nor is it predictable.

回答2:

You can actually

    class MyClass {
        constructor(input1, input2){
             this.in1 = input1;
             this.in2 = input2;
         }

    }
    let myObject = {};


    try {
         myObject = {
             classHandler: new MyClass('1','2')
         }
    } catch (e) {
    } finally {
        delete myObject.classHandler
    }
