# Semicolons

Semicolons `;` are used as statement separators. A semicolon can be placed after any statement, but can be omitted if only one statement appears on the line. Semicolons must be used to separate multiple statements if they appear on the same line – exactly one semicolon between each pair of statements.

```
// Declare a constant, without a semicolon.
//
let a = 1

// Declare a variable, with a semicolon.
//
var b = 2;

// Declare a constant and a variable on a single line, separated by semicolons.
//
let d = 1; var e = 2

// Invalid: Multiple semicolons between statements.
let f = 1;; let g = 2
