I want to get a enum from object, in typescript, is it possible? Example below!
const keys = ['a', 'b', 'c', 'd', 'e']
const values = [1, 2, 3, 4, 5]
// expected result
enum result {
a = 1,
b = 2,
c = 3,
d = 4,
e = 5
}

No you can not get an enum, which is a pre-defined type.
What you are trying to get is a mapping between the two arrays (dictionary/object), you can create it dynamically if they are always in the correct order.
const keys = ['a', 'b', 'c', 'd', 'e']
const values = [1, 2, 3, 4, 5]
// mapping
let dictionary = {};
keys.forEach((key, i) => dictionary[key] = values[i]);
console.log(dictionary);

yep, I already do that, get key:value pair object from array, but I want to know, is there any possibility to get enum from object or build enum dynamically

@GevorgMartirosyan Doesn't "No you can not get an enum, which is a pre-defined type" answer your question? TypeScript is compiled into JavaScript. At runtime (which is where the "dynamic" code runs), enums don't exist. But this feels like an XY problem.

yeah, you already answer, thank you a lot!
