This is the most robust display option. It takes a string of tokens and replaces them with their corresponding values.
moment().format(); // "2014-09-08T08:02:17-05:00" (ISO 8601)
moment().format("dddd, MMMM Do YYYY, h:mm:ss a"); // "Sunday, February 14th 2010, 3:25:50 pm"
moment().format("ddd, hA"); // "Sun, 3PM"
moment('gibberish').format('YYYY MM DD'); // "Invalid date"| Token | Output | |

Note: as of 1.6.0, the z/zz format tokens have been deprecated from plain moment objects. Read more about it here. However, they *do* work if you are using a specific time zone with the moment-timezone addon. |

X was added in 2.0.0.
e E gg gggg GG GGGG were added in 2.1.0.
x was added in 2.8.4.
SSSS to SSSSSSSSS were added in 2.10.5. They display 3 significant
digits and the rest is filled with zeros.
k and kk were added in 2.13.0.
Because preferred formatting differs based on locale, there are a few tokens that can be used to format a moment based on its locale.
There are upper and lower case variations on the same formats. The lowercase version is intended to be the shortened version of its uppercase counterpart.

To escape characters in format strings, you can wrap the characters in square brackets.
moment().format('[today] dddd'); // 'today Sunday'Note: While these date formats are very similar to LDML date formats, there are a few minor differences regarding day of month, day of year, and day of week.
For a breakdown of a few different date formatting tokens across different locales, see this chart of date formatting tokens.

If you are more comfortable working with strftime instead of LDML-like parsing tokens, you can use Ben Oakes' plugin. benjaminoakes/moment-strftime.
As of version 1.5.0, calling moment#format without a format will default to moment.defaultFormat. Out of the box, moment.defaultFormat is the ISO8601 format YYYY-MM-DDTHH:mm:ssZ.
As of version 2.13.0, when in UTC mode, the default format will return Z as the offset, instead of +00:00.
