An example of an AI chatbot conversation about using variables in JavaScript.
How do I use variables in JavaScript?
In JavaScript, variables are used to store data values. You can declare a variable using var, let, or const.
What's the difference between let and const?
let allows you to reassign the variable later, while const creates a constant variable that cannot be reassigned.
Can you give me an example of using a variable?
Sure! Here's a simple example: let age = 25; console.log(age); This will output 25 to the console.
What are the best practices for naming variables?
Use descriptive names, avoid starting with numbers, and use camelCase for multi-word names, like userName.
