Declarando um método fora do construtor

/*for methods declared outside the constructor remember:
do not add a function/const..it is fn= ()=>{} and NOT const fn = ()=>{} if outside the constructor
access them in the constructor with this.methodName;
the same method CAN access this.name below.
They (method declared inside and outside) work.

return result;
}

let r =await fetch('/test', {method: 'POST', body: JSON.stringify({name:this.name}), headers: {'Content-type': 'application/json; charset=UTF-8'}})
