How would I programmatically call an object method? Like MyObject.XVariable(//some function)
I have an object, that takes input from an API call to fill it up.
let MyDog =
Name: 'Dog',
let arrayFunctions;
fetchDogsFunctions(dogAPIUrl).then(res =>
//results is an array that has a list of functions the dog has, like //getStats(), or walkDog()
arrayFunctions = res;
)
Now I want to map through the array results and call the function on my dog like...
arrayFunctions.map(item =>
await MyDog.item(//Params)
)
How can I do this??
Where MyDog is set up from a file, and then depending on the array functions, for each function it programmatically fills in the call to the new function like MyDog.item where item is a variable in an array called "Walk()"

I assumed how your data might have structured. Pls take a look below and you might get the idea of how to call functions dynamically using "await"
const MyDog =
funA(a) return Promise.resolve('Function A called with parameter ' + a)
, funB(b) return Promise.resolve('Function B called with parameter ' + b)
const arrayFunctions = ['funA', 'funB']
Promise.all(arrayFunctions.map(async (item, i) =>
await MyDog[item](++i))
)
