Destructuring an array of strings for use as parameters

Hey guys, I'm working with an array of keys here

Example 1:

let keyArray = ['x', 'y', 'z']

I'm trying to find a way to use these keys as parameters without repeating them multiple times. Do you have any suggestions on how to do this?

Example 2:

const [...keyArray] = someFunction(keyArray)

This way, I can easily use them as parameters like so:

const name = x.name
  • However, it seems that Example 2 is not functioning as expected.

Answer №1

When iterating through an array, you can utilize the bracket parameter syntax like this:

const data: {[property: string]: any} = processData(arrayWithData)
for (item of arrayWithData) { // or (item in data)
  manipulateData(data[item])
}

Creating multiple local variables based on the array's elements may not be the most efficient approach. Storing the results from processData in an object would be a better alternative.
