# 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:

`if (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.
