Primitive Literals

Strings should always use double quotes (never single quotes) and should always appear on a single line. Never use a slash to create a new line in a string.

// Good
var name = "Nicholas";

// Bad: Single quotes
var name = 'Nicholas';

// Bad: Wrapping to second line
var longString = "Here's the story, of a man \
named Brady.";

Numbers should be written as decimal integers, e-notation integers, hexadecimal integers, or floating-point decimals with at least one digit before and one digit after the decimal point. Never use octal literals.

// Good
var count = 10;

// Good
var price = 10.0;
var price = 10.00;

// Good
var num = 0xA2;

// Good
var num = 1e23;

// Bad: Hanging decimal point
var price = 10.;

// Bad: Leading decimal point
var price = .1;

// Bad: Octal (base 8) is deprecated
var num = 010;
