Summary  
This chapter covers using the else keyword alongside if statements to implement branching logic that executes alternative code blocks when a condition evaluates to false.

General domain of usage  
Control flow for decision-making in applications

While `if` statements execute code under specific conditions, they don't create true branching in your code. Instead, they guide the interpreter through different paths within your program.

## The else Keyword
To introduce branching behavior, you can use the `else` keyword in combination with `if` to create conditional statements.

let a = 60;

if (a >= 100) {
  console.log("a is greater than or equal to 100");
} else {
  console.log("a is less than 100");
}

In the example above, the condition `a >= 100` evaluates to `false`, so the code block within the `if` statement is not executed. Instead, the code block within the `else` statement is executed because the `if` condition is `false`.

The syntax of the `else` statement is similar to that of the `if` statement, except it doesn't require a condition or parentheses `()`.

> Note
>
> When using an `else` statement, do not place the **end-of-command** (`;`) after the `if` code block (`{}`), as this will result in a `SyntaxError`. The `if-else` statement is considered a single command.
