About Me

Hello, I am Amritanjali and I welcome you to my blog UI Source where I write about UI related technologies like Angular, TypeScript, JavaScript, HTML, CSS.

I love to create my own thoughts about anything which comes to my notice and I think we should always have our own thinking on everything rather than just following what others think.

That’s why I have started writing this blog to keep all my notes and thoughts on UI related technologies in one place and make them available to others.

Thanks for visiting UI Source and I hope you enjoyed the posts. Any kind of feedback is always welcomed and appreciated. You can submit any query or suggestion in the Contact Us box.

Finally, I understood sometimes we even used a closure without realizing we were using a closure. First, understand the meaning of closure “an act or process of closing something”, now we can relate closure in javascript, closure is an inner function which wraps inside the outer function, which can access outer function scope & global function scope. for scoping you can read my previous blog:- http://uisource.blogspot.com/2018/08/javascript-variable-scoping.html why do we create?
