calling resolve from callback function in angular

Question

In my angular application i have to return the resolve form a the function callback.

Sample code:

new testPromise=new Promise((resolve,reject)=>{
   abc("test",successCallback,errorCallback)    
});

How can i call the resolve/reject from the callback functions

such as:

successCallback(data){
  resolve(data);

}
errorCallback(error){
  reject(error);
}

Is this possible or will i have to call the resolve/reject from inside the promise only?

Just pass them directly as the callback arguments:

let testPromise = new Promise((resolve, reject) => {
    abc("test", resolve, reject);
});

Do not create separate functions such as function successCallback(data) { resolve(data); } inside the promise constructor.
