Problem statementSend feedbackYou are given three arrays containing the id, name, and image of users.ObjectivesCreate a function with a name createUserObjects that takes three arrays as a parameter and returns an array of objects representing the user. Use the map function to create objects from the arrays.The mapping should be done in such a way that for the first object, the first element of all arrays should be used, and so on.Input:const ids = [1, 2, 3];const names = ["John", "Jane", "Alice"];const images = ["john.jpg", "jane.jpg", "alice.jpg"];createUserObjects(ids,names,images);
Solution
Sure, here is the solution in JavaScript:
function createUserObjects(ids, names, images) {
return ids.map((id, index) => {
return {
id: id,
name: names[index],
image: images[index]
};
});
}
const ids = [1, 2, 3];
const names = ["John", "Jane", "Alice"];
const images = ["john.jpg", "jane.jpg", "alice.jpg"];
console.log(createUserObjects(ids, names, images));
This function createUserObjects takes three arrays as parameters. It uses the map function to create a new array of objects. For each object, it uses the corresponding elements from the ids, names, and images arrays. The map function does this by taking a function as an argument, which is called for each element in the array. The function is passed the current element and its index. We use the index to get the corresponding elements from the names and images arrays.
