JavaScript fundamental (ES6 Syntax): Exercise-147 with Solution

Serialize Cookie Name-Value to Set-Cookie Header

Write a JavaScript program to serialize a cookie name-value pair into a Set-Cookie header string.

• Use template literals and encodeURIComponent() to create the appropriate string.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2

// Define the serializeCookie function
const serializeCookie = (name, val) => `${encodeURIComponent(name)}=${encodeURIComponent(val)}`;

// Serialize a cookie with name 'foo' and value 'bar'
console.log(serializeCookie('foo', 'bar')); // Output: "foo=bar"

Output:

foo=bar
