Today we are going to learn about Angular Basics  Let's get start... What is Angular         -    Angular is TypeScript Based open-source front-end platform.          -    Using angular we can create our application on the web and mobile side.         -    Angular is created and managed by Google.         -    It provides some features like component, directive, module, services, and end to                 end tooling. Features of Angular 1. DOM ( Document Object Model ) 2. TS ( Type-Script ) 3. Data Binding 4. Testing 1. DOM ( Document Object Model )    - In Angular, we are using regular DOM.   - Suppose we are updating 6 instances on the same HTML page.     In that case, angular is going to update the entire tree structure of HTML tags.   2. TS ( Type-Script )   - TypeScript is the superset of JS ( Javascript ).  - In the browser, It’s compiled into Plan JavaScript.  - TypeScript is created and managed by Microsoft. It provides some    feat

Java-Script Rest and Spread Operators:  In JavaScript, we are using three dots ( ... ) for both REST and SPREAD Operators. But these two operators are not the same they both have a different purpose. REST Operator - Purpose of this operator is to collect all remaining elements into the array. - For Example:           - let take one array in below example      - O/P :       Necklace [ 'Earring', 'Payal', 'Brooch', 'Bangles']   - In the Above example three-dot contain the rest of the product time in the restProdcut variable that calls Destructuring that breaks our code into small pieces.   - so in the above example, mainProduct variable contains my Main product and restProduct varibale contains my rest products.   - The rest operator always gives rest data into array format only.   - while creating function we can also use rest operator like below SPREAD Operator:  - It's work opposite to rest operators, like in rest operator we are collecting item
