What is this ?

this is a js validation library, works on the browser as well as on the server, it is well tested with the help of QUnit. hope you find it helpful.

On the Browser:

if you want to use "itiz" on the browser, just download and then load the itiz.min.js file.

    <script src='./your_project/path/to/itiz.min.js'></script>

if you are using some server side js frameworks like Nodejs, you just need to npm install it

    npm i itiz 

and the simply require it as you do with any other package

    // or false if the email is not valid

    itiz('this is a long string').length({max: 20});

params parameters are required, and it must be an object that has one of this: min: the minimum length of the string max: the maximum length of the string

.same()

this method will ensure if two (or more) values are the same (equal) usage

    // this will return an object (wich is a chain of all the other method or false if the two values are not the same
    itiz(['password_123', 'password_123']).same();

    // You can pass as many values as you can to check if they are all the same
