Is possible to obtain in sum result of a function ? Not function itself, just result.
let a = 1;
let b = 2;
let object = {
dummy: 'dummy text',
sum: function () {
a + b
},
}
console.log(object) // { dummy: 'dummy text', sum: [Function: sum] }
I want to obtain : { dummy: 'dummy text', sum: 3 } I don't want to use an external function
If you want a simple static value, you could simply assign a + b as the value for sum. Otherwise you'd need to invoke sum method call.
let a = 1;
let b = 2;
let object = {
dummy: 'dummy text',
sum: a + b,
}
console.log(object) // { dummy: 'dummy text', sum: 3 }You just need to execute the function instead of initializing it.
This can be done by instantiating the function before and then call it when creating the object.
let a = 1;
let b = 2;
const sum = (a, b) => a + b
let object = {
dummy: 'dummy text',
sum: sum(a, b)
}
console.log(object)Use an IIFE if you want to assign the result of a function invocation to sum
let a = 1;
let b = 2;
let object = {
dummy: 'dummy text',
sum: (function () {
return a + b;
})(),
};
console.log(object);
