Statements

Statements are list of programming instructions used to control specific actions in JavaScript. JavaScript statements are made of:

  • Values
  • Operators
  • Expressions
  • Keywords
  • Comments

Semicolon​

Semicolon indicates the end of a statement. If semicolon is not inserted, the next line could be taken as an extension of the first.

var x = 1;
var y = 2 + x;
var z = 3 + y;
console.log(x, y, z);
// expected output: 1 3 6

When semicolon is not used, the interpreter will take next line as a continuation for the current line.

Note

We can group multiple statements together in one line by separating them by a semicolon. Even though JavaScript ignores multiple spacing, it is standard practice to use a semicolon at the end of a statement.
