Using JSON.stringify on custom class

Question

I\'m trying to store an object in redis, which is an instance of a class, and thus has functions, here\'s an example:

function myClass(){
    this._attr = \"         


        

Answer 1

it looks like you attempt to stringify a closed function. you can use ()=>{} to solve the scope problem.

function myClass(){
    this._attr = "foo";
    this._accessCounts = 0;
    this.getAttr = ()=>{
        this._accessCounts++;
        return this._attr;
    }
    this.getCount = ()=>{
        return this._accessCounts;
    }
}
