if-else construct in JavaScript

Now we will study the special construct if-else, which allows some code to be executed depending on some condition.

Using the construct if-else, we can ask the program, for example, the question "is the variable a greater than the variable b", and depending on the answer, execute one code or another.

The construct syntax looks like this:

javascriptif (comparison operation) {
  /*
    the code written here will be executed if the 
    result of the comparison operation is true
  */
} else {
  /*
    the code located here will be executed if the 
    result of the comparison operation is incorrect
  */
}

There are many operators for comparison operations in JavaScript. Let's get started studying them.
