Literal

Literals represent values in JavaScript. These are fixed values?not variables?that you literally provide in your script.

Examples

String literals

A string literal is zero or more characters enclosed in double ( " ) or single quotation marks ( ' ). A string must be delimited by quotation marks of the same type (that is, either both single quotation marks, or both double quotation marks).

The following are examples of string literals:

js 
"foo"
;

"bar"
;

"1234"
;

"one line \n new line"
;

"Joyo's cat"
;

Object literals

An object literal is a list of zero or more pairs of property names and associated values of an object, enclosed in curly braces ( {} ).

The following is an example of an object literal. The first element of the car object defines a property, myCar , and assigns to it a new string, " Toyota "; the second element, the getCar property, is immediately assigned the result of invoking the function carTypes('Honda') ; the third element, the special property, uses an existing variable ( sales ).

js 
const
 sales 
=
 "BMW"
;


function
 carTypes
(
name
)
 {

  return
 name 
===
 "Honda"
 ?
 name 
:
 `
Sorry, we don't sell 
${
name
}
.
`
;

}


const
 car 
=
 {

  myCar
:
 "Toyota"
,

  getCar
:
 carTypes
(
"Honda"
)
,

  special
:
 sales
,

}
;


console
.
log
(
car
.
myCar
)
;
 // Toyota

console
.
log
(
car
.
getCar
)
;
 // Honda

console
.
log
(
car
.
special
)
;
 // BMW
