$3


Creates a new Match instance.

Events you can listen to:

- deactivate (HTMLElement): Triggered when the block is deactivated.
- activate (HTMLElement): Triggered when the block is activated.
- pair-flip (HTMLElement, HTMLElement): After a pair flip.
- success (HTMLElement, HTMLElement): When a match is found.
- win (Number): Emitted when the game is over (the first argument is a
number representing the number of miliseconds from the moment the game
was started to now).
- render (currentElement, data, isDuplicate): Emitted on render–the HTML
element can be modified which will end in the editing the HTML. The data
object is the current data object reference. The isDuplicate parameter
takes a value of 0 or 1 (when the match is rendered).
- time (Number): Like win, but emitted every second, during the game.

#### Params

- Element|String elm: The HTML element or the query selector.
- Object options: An object containing the following fields:
- autoremove (Boolean): If true, the blocks will be removed when they are matching (default: true).
- size (Object):
- x (Number): How many blocks per row (default: 4).
- y (Number): How many blocks per column (default: 4).
- classes (Object):
- active (String): The active class added the active block elements (default: "active").
- step (Object):
- x (Number): How much should be increased the x coordinate for each block.
- y (Number): How much should be increased the y coordinate for each block.
- Array data: Array of objects used in the templating.

#### Return
- Match The Match instance.

$3

Checks if two elements match together.

#### Params

- HTMLElement elm1: The first element.
- HTMLElement elm2: The second element.

#### Return
- Boolean true if the elements make a match or false otherwise.

$3


Attaches a new event listener (on("some-event", fn)).

#### Return
- Match The Match instance.

$3


Emits an event data data as arguments (emit("some-event", and, data, here)).

#### Return

$3

Shuffles a given array.

#### Params

- Array arr: The array to shuffle (default: this.data).

#### Return
- Array The shuffled array.

$3

Clears the container HTML.

#### Return
- Match The Match instance.

$3

:sparkling_heart: Support my projects

I open-source almost everything I can, and I try to reply to everyone needing help using these projects. Obviously,
this takes time. You can integrate and use these projects in your applications for free! You can even change the source code and redistribute (even resell it).

However, if you get some profit from this or just want to encourage me to continue creating stuff, there are few ways you can do it:


- Starring and sharing the projects you like :rocket:
- [![Buy me a book][badge_amazon]][amazon]—I love books! I will remember you after years if you buy me one. :grin: :book:
- [![PayPal][badge_paypal]][paypal-donations]—You can make one-time donations via PayPal. I'll probably buy a ~~coffee~~ tea. :tea:
- [![Support me on Patreon][badge_patreon]][patreon]—Set up a recurring monthly donation and you will get interesting news about what I'm doing (things that I don't share with everyone).
- Bitcoin—You can send me bitcoins at this address (or scanning the code below): 1P9BRsmazNQcuyTxEqveUsnf5CERdq35V6
