Sign Up and Sign in Page

This code presents a web page containing a login form and a sign-up form, along with some necessary code to validate inputs and execute login and sign-up operations. Here's a brief explanation of each part of the code:

1) Sign-In Form:

.Provides fields to input an email address and a password

When the "Sign in" button is clicked, it verifies whether the information is correct or not, using locally stored data in the localStorage

.Displays an alert if the information provided is incorrect

2) Sign-Up Form:

.Allows users to input a username, an email address, and a password

.Validates the match between the password and its confirmation

.Upon successful form submission, the information is stored locally using localStorage

3) Data Validation:

.JavaScript is used to validate the accuracy of the information entered in both the sign-up and sign-in forms

.It verifies the password match in the sign-up form and validates login information using locally stored data

Thus, the code provides an interactive user interface for users to log in or sign up, with the ability to verify input accuracy and execute appropriate operations based on that
