+1. ### Add a key-value pair in object conditionally
+
+   Spread operator is used to spread one object and conditional operator && to achieve the task conditionally
+
+   1. **While defining the object:**
+
+      We are injecting the new property at time of defining the object only
+
+      ```javascript
+         const is_employee=true;
+         const student={
+            name:'Krishna Kant',
+            roll:'AD203',
+            stream:'MERN stack web development',
+            ...(is_employee && {company:'Inventives.ai})
+         }
+      ```
+
+     2. **After object has been defined**
+
+      We are injecting the new property after the object has been defined with its default key value pairs.
+
+      ```javascript
+         const is_employee=true;
+         let student={
+            name:'Krishna Kant',
+            roll:'AD203'
+         }
+        is_employee && student={
+            ...student,
+            current_company:'Inventives.ai'
+        }
+      ```

+## Disclaimer
+
+The code snippets mentioned in this repository are the summary of frequently used codes in Javascript and/or React with ES6 syntax. We cannot guarantee that only these snippets will actually make the code cleaner, smoother and optimised, nor should you focus on copying and pasting them all. The primary purpose is for you to get a sense of how some bulk codes might be replaced with one-liner ES6 conditional and operational statements!

+
+Happy Coding 😊
