How to usea custom function in Javascript
The approach involves a custom function that takes arrays of keys and values as arguments. It iterates through the arrays, assigning properties to the object with corresponding keys and values.
Example: The example uses a custom function to create an object with numerical keys and corresponding string values from arrays.
function createObject(keys, values) {
const object = {};
for (let i = 0; i < keys.length; i++) {
object[keys[i]] = values[i];
}
return object;
}
const keys = [0, 1, 2];
const values =
["w3wiki", "Hello JavaScript", "Hello React"];
const object = createObject(keys, values);
console.log(object);
Output
{ '0': 'w3wiki', '1': 'Hello JavaScript', '2': 'Hello React' }
How to create an object from the given key-value pairs using JavaScript ?
In this article, we will learn to create an object from the given key-value pairs using JavaScript.Key-value pair: Unique identifier (key) associated with its corresponding value; fundamental for data organization and retrieval in programming. here we have some common approaches.
We will explore the process of creating objects from key-value pairs in JavaScript. Key-value pairs are fundamental in organizing and retrieving data efficiently within programs. We’ll discuss various common approaches to achieve this goal, empowering you with the knowledge to handle key-value data effectively in your JavaScript projects. Let’s see and discover these approaches together.
Following are some approaches to achieve the mentioned target.
