Ternary operator in Javascript - Mini Project: Build & Apply

Using the Ternary Operator in JavaScript

📖 Scenario: You are creating a simple program to check if a person is old enough to vote. Voting age is 18 years or older.

🎯 Goal: Build a program that uses the ternary operator to decide if a person can vote based on their age.

📋 What You'll Learn

Create a variable called age with a specific number value.

Create a variable called votingAge and set it to 18.

Use the ternary operator with age and votingAge to create a variable canVote that holds the string 'Yes' or 'No'.

Print the value of canVote.

💼 Career

Understanding the ternary operator helps write clean and concise code, a useful skill for any developer.

1

Set the person's age

Create a variable called age and set it to 20.

Javascript

// Your code here

Need a hint?

Use const age = 20; to create the variable.

2

Set the voting age limit

Create a variable called votingAge and set it to 18.

Javascript

const age = 20;
// Your code here

Need a hint?

Use const votingAge = 18; to set the voting age.

3

Use the ternary operator to check voting eligibility

Create a variable called canVote that uses the ternary operator to check if age is greater than or equal to votingAge. If yes, set canVote to 'Yes', otherwise 'No'.

Javascript

const age = 20;
const votingAge = 18;
// Your code here

Need a hint?

Use the ternary operator like this: condition ? valueIfTrue : valueIfFalse.

4

Print the voting eligibility

Write a console.log statement to print the value of canVote.

Javascript

const age = 20;
const votingAge = 18;
const canVote = age >= votingAge ? 'Yes' : 'No';
// Your code here

Need a hint?

Use console.log(canVote); to show the result.
