I recently faced an issue where I needed to extract from an API object values that used dynamic keys. Here’s how I resolved this issue:

function destructureObj(obj: {[key: string]: string}, key: string) {

    return [...Object.values(key)]
}

destructureObj(country, country.languages);

Let’s break down what the function above does:

• The first parameter takes an object with a key of type string and it’s values are of type string.
• The second parameter is a string.
• We use destructuring along with using Object.values() in order to return the values of the key that we want in the object.
