+## GAP TASK
+
+## Starting of project
+
+# Locally
+Run index.html file.
+# In IDE
+Run index.html in live server.
+
+
+## Testing
+
+# npm test or npm run test
+To run tests, you need to install Jest first:  
+npm install --save-dev jest  
+Then you can use the following commands for different actions:
+# To Test a Single File
+bash$ npx jest filename.test.js 
+# To Test All Files in a Directory
+bash$ npx jest directoryname
+# Watching Files
+bash$ npx jest -w  
+Watch Usage
+ › Press f to run only failed tests.
+ › Press o to only run tests related to changed files.
+ › Press p to filter by a filename regex pattern.
+ › Press t to filter by a test name regex pattern.
+ › Press q to quit watch mode.
+ › Press Enter to trigger a test run.
+
+## Test Coverage
+
+# npm run coverage
+To check the number of line code covered in the jest tests.
+
+
+
+## Client requirements of Project 
+Frontend Javascript question
+# Problem Create the following UI:
+- Create an empty container div in the HTML file.
+- Programmatically create multiple child divs in the container, say 10. Use 
+Javascript.
+- Give all the child divs a black background.
+- Lay out the child divs horizontally within the container.
+- Whenever the user clicks one of the child divs, the child div should respond as 
+follows:
+ - If the child div does not have a blue background:
+ - Give the child div a blue background.
+ - Print out the child div's index. If the 7th div is getting a blue background, 
+say "Turning ON 7".
+ - If the child div does have a blue background:
+ - Give the child div its original background color.
+ - Print out the child div's index. If the 4th div is removing the blue 
+background, say "Turning OFF 4".
+# Requirements:
+- Should work for 3, 10, 27, however many child divs. They do not all need to be on 
+the same line, but they should still lay out horizontally (across multiple lines if 
+necessary).
+- Combine HTML, CSS, and JavaScript
