I am a beginner in Typescript, and I am looking for a neat way to convert all the arrays in an object to a set.
Input:
const inputObject = {'a': [1, 2, 3], 'b': [2, 2, 2], 'c': [3,3,2,4]};
Output
{'a': Set(3){1, 2, 3}, 'b': Set(1){2}, 'c': Set(3){2, 3, 4};
I know how to work on it iteratively key by key and get the solution. I am looking if I can do it more elegantly and modify the same inputObject instead of creating a new object.
I think this code Works fine!
const inputObject = {'a': [1, 2, 3], 'b': [2, 2, 2], 'c': [3,3,2,4]};
for (const key in inputObject ) {
inputObject[key] = new Set(inputObject[key]);
}
console.log(inputObject);
This code works, but not sure why it isn't working in StackOverflow's code editor.
You need to do the following
Set.const inputObject = {'a': [1, 2, 3], 'b': [2, 2, 2], 'c': [3,3,2,4]};
console.log(inputObject);
Object.keys(inputObject).forEach(key => inputObject[key] = new Set(inputObject[key]));
console.log(inputObject);
