How Can I Retrieve a Specific Cookie's Value by Name in JavaScript?

Get Cookie by Specific Name

In your code, you have a getter that retrieves values from all cookies and splits them into an array. You want to modify it to retrieve values only from a specific cookie named "obligations=".

Solution:

To achieve this, you can use the following approach:

function getCookie(name) {
  const value = `; ${document.cookie}`;
  const parts = value.split(`; ${name}=`);
  if (parts.length === 2) return parts.pop().split(';').shift();
}

Walkthrough:

• Split the cookies string into two parts: one before and one after the name and equals sign ("; {name}=") of the desired cookie.
• If the split resulted in two parts, it means the cookie exists.
• Pop the second part, which contains the value and the remaining cookies string.
• Split the remaining string by ";" to get the value of the desired cookie.
• Shift the first part of the split result to get the actual value.
