+# Tasks
+Please complete the following tasks and post them on the tapaScript Discord under "40 Days of JavaScript".
+
+> Please note that none of the answers need you to create any UI. Just focus on the logic building and print the output on the browser console.
+
+## 1. Odd or Even?
+ - [ ] Take a number and find if the number is an odd or even number.
+ - [ ] Print the number and result in the console.
+
+## 2. Do you have a Driving License?
+Let's check if you are eligible to get a driving license. The eligibility to get a driving licence is 18 years.
+
+- [ ] Manage `age` as a variable.
+- [ ] Check if the age is elligible for a driving license and print it on the console accordingly.
+
+## 3. Calculate CTC with a Bonus
+Let's calculate how much you earn from your office.
+
+- [ ] You get 12,300 rupees as your monthly salary.
+- [ ] You get a 20% bonus on your annual salary.
+- [ ] How much money do you make per annum as a CTC?
+
+## 4. Write a program for the Traffic Light Simulation.
+Red Light... Green Light... Let's Play!
+
+- [ ] Create a `color` variable.
+- [ ] Based on the color variable's value print in the console if a traveller needs to STOP or GO. The Red color is for STOP and the Green color is for GO.
+
+## 5. Create an Electricity Bill Calculator
+Let's calculate how much you pay for electricity bills per month and annually.
+
+- [ ] Create a `units` variable. Based on this value you will calculate the total electricity bill for a months.
+- [ ] If each day you consume the `units` and each unit cost 150 rupees, how much will you be charged per month?
+- [ ] If there is a 20% discount on the annual payment, how much will you be charged for an annual payment?
+
+## 6. Leap Year Checker
+Is 2025 a Leap Year?
+
+- [ ] Take `year` as input.
+- [ ] Use the arithmetic operator and ternary operator to print if a year is a leap year or not.
+
+## 7. Max of Three Numbers
+Find the max number from the lot.
+
+- [ ] Take three numbers and assign them to variables p, q, and r.
+- [ ] Now find the maximum of these three numbers using the comparison operators.
+
+## 8. Biwise Doubling
+A tricky one for you
+
+- [ ] Create a variable `count` and assign  a value, say, 5.
+- [ ] Now use the Bitwise shift operator to make the number double.
+- [ ] Print it on the console.
