Listing 3.13 - A calendar event

var event = {
    title : "Appraisal Meeting",
    startDate : "2016-10-04 16:00:00",
    endDate : "2016-10-04 17:00:00",
    location : "Martha's office",
    importance: 1,
    notes : 'Don\'t forget the portfolio!'
};

Listing 3.13 - A calendar event - Task 4

Add a backslash to the location property.
Log the location property.

var event = {
    title : "Appraisal Meeting",
    startDate : "2016-10-04 16:00:00",
    endDate : "2016-10-04 17:00:00",
    location : "Martha\'s office",    // add a backslash
    importance: 1,
    notes : 'Don\'t forget the portfolio!'
};

console.log(event.location);    // log the location

The backslash has no effect. The single quotation mark works without the backslash and with the backslash.

Listing 3.13 - A calendar event - Task 5

Include a backslash in a string so it will be displayed.

var event = {
    title : "Appraisal Meeting",
    startDate : "2016-10-04 16:00:00",
    endDate : "2016-10-04 17:00:00",
    location : "Martha's off\\ice",    // include a backslash
    importance: 1,
    notes : 'Don\'t forget the portfolio!'
};

console.log(event.location);    // display the string with the backslash

A single backslash is used for escape sequences, to specify characters that you cannot type directly.

To include an actual backslash in a string, use a double backslash: \\.

The double backslash is an escape sequence that specifies a backslash.
