Declaring Variables

A computer program is a set of rules that tell a computer what to do.These rules are written in a special language called programming language, and they are known as statements.

Now, we can talk about JavaScript variables. Variables are like containers that hold information. Think of them as labeled boxes where you can store numbers, words, or other types of data.

When you create a variable, you give it a name, so you can easily find and use it later in your program. For example, if you want to keep track of someone's age, you could create a variable called age and store the number in it.

Variables can be changed throughout your program, so you can update the information they hold as needed.

To declare a variable in JavaScript, you need to use the let keyword, followed by the name you want to give to your variable. To assign a value to your variable, you can use the equal sign =, followed by the value you want to store. For example, if you want to create a variable to store someone's age, you can write:

Loading Code . . .

Notice that we use semicolons ; at the end of each statement. In JavaScript, a semicolon is used to mark the end of a statement. It tells JavaScript that you're done writing a particular instruction and you're moving on to the next one. While using semicolons is not always required in JavaScript, it's considered a best practice to include them at the end of each statement. This can help avoid errors and make your code easier to read and understand.

Now, try to declare a variable called myAge with any number; Then, print the variable with the console.log command.
