### new Datastore(options)
<p>Create a new collection, either persistent or in-memory.</p>
<p>If you use a persistent datastore without the <code>autoload</code> option, you need to call <code>loadDatabase</code> manually. This
function fetches the data from datafile and prepares the database. <strong>Don't forget it!</strong> If you use a persistent
datastore, no command (insert, find, update, remove) will be executed before <code>loadDatabase</code> is called, so make sure
to call it yourself or use the <code>autoload</code> option.</p>
**Params**
- options <code>object</code> | <code>string</code> - <p>Can be an object or a string. If options is a string, the behavior is the same as in
v0.6: it will be interpreted as <code>options.filename</code>. <strong>Giving a string is deprecated, and will be removed in the
next major version.</strong></p>
- [.filename] <code>string</code> <code> = null</code> - <p>Path to the file where the data is persisted. If left blank, the datastore is
automatically considered in-memory only. It cannot end with a <code>~</code> which is used in the temporary files NeDB uses to
perform crash-safe writes.</p>
- [.inMemoryOnly] <code>boolean</code> <code> = false</code> - <p>If set to true, no data will be written in storage.</p>
- [.timestampData] <code>boolean</code> <code> = false</code> - <p>If set to true, createdAt and updatedAt will be created and
populated automatically (if not specified by user)</p>
- [.autoload] <code>boolean</code> <code> = false</code> - <p>If used, the database will automatically be loaded from the datafile
upon creation (you don't need to call <code>loadDatabase</code>). Any command issued before load is finished is buffered and
will be executed when load is done. When autoloading is done, you can either use the <code>onload</code> callback, or you can
use <code>this.autoloadPromise</code> which resolves (or rejects) when autloading is done.</p>
- [.onload] <code>function</code> - <p>If you use autoloading, this is the handler called after the <code>loadDatabase</code>. It
takes one <code>error</code> argument. If you use autoloading without specifying this handler, and an error happens during
load, an error will be thrown.</p>
- [.beforeDeserialization] <code>function</code> - <p>Hook you can use to transform data after it was serialized and
before it is written to disk. Can be used for example to encrypt data before writing database to disk. This
function takes a string as parameter (one line of an NeDB data file) and outputs the transformed string, <strong>which
must absolutely not contain a <code>\n</code> character</strong> (or data will be lost).</p>
- [.afterSerialization] <code>function</code> - <p>Inverse of <code>afterSerialization</code>. Make sure to include both and not
just one, or you risk data loss. For the same reason, make sure both functions are inverses of one another. Some
failsafe mechanisms are in place to prevent data loss if you misuse the serialization hooks: NeDB checks that never
one is declared without the other, and checks that they are reverse of one another by testing on random strings of
various lengths. In addition, if too much data is detected as corrupt, NeDB will refuse to start as it could mean
you're not using the deserialization hook corresponding to the serialization hook used before.</p>
- [.corruptAlertThreshold] <code>number</code> <code> = 0.1</code> - <p>Between 0 and 1, defaults to 10%. NeDB will refuse to start
if more than this percentage of the datafile is corrupt. 0 means you don't tolerate any corruption, 1 means you
don't care.</p>
- [.compareStrings] [<code>compareStrings</code>](#compareStrings) - <p>If specified, it overrides default string comparison which is not
well adapted to non-US characters in particular accented letters. Native <code>localCompare</code> will most of the time be
the right choice.</p>
- [.nodeWebkitAppName] <code>string</code> - <p><strong>Deprecated:</strong> if you are using NeDB from whithin a Node Webkit app,
specify its name (the same one you use in the <code>package.json</code>) in this field and the <code>filename</code> will be relative to
the directory Node Webkit uses to store the rest of the application's data (local storage etc.). It works on Linux,
OS X and Windows. Now that you can use <code>require('nw.gui').App.dataPath</code> in Node Webkit to get the path to the data
directory for your application, you should not use this option anymore and it will be removed.</p>

<p><strong>WARNING:</strong> The API was changed between v1.7.4 and v1.8, for consistency and readability reasons. Prior and
including to v1.7.4, the callback signature was (err, numAffected, updated) where updated was the updated document
in case of an upsert or the array of updated documents for an update if the returnUpdatedDocs option was true. That
meant that the type of affectedDocuments in a non multi update depended on whether there was an upsert or not,
leaving only two ways for the user to check whether an upsert had occured: checking the type of affectedDocuments
or running another find query on the whole dataset to check its size. Both options being ugly, the breaking change
was necessary.</p>

<a name="query"></a>
## query : <code>Object.&lt;string, \*&gt;</code>
<p>Nedb query.</p>
<p>Each key of a query references a field name, which can use the dot-notation to reference subfields inside nested
documents, arrays, arrays of subdocuments and to match a specific element of an array.</p>
<p>Each value of a query can be one of the following:</p>
<ul>
<li><code>string</code>: matches all documents which have this string as value for the referenced field name</li>
<li><code>number</code>: matches all documents which have this number as value for the referenced field name</li>
<li><code>Regexp</code>: matches all documents which have a value that matches the given <code>Regexp</code> for the referenced field name</li>
<li><code>object</code>: matches all documents which have this object as deep-value for the referenced field name</li>
<li>Comparison operators: the syntax is <code>{ field: { $op: value } }</code> where <code>$op</code> is any comparison operator:
<ul>
<li><code>$lt</code>, <code>$lte</code>: less than, less than or equal</li>
<li><code>$gt</code>, <code>$gte</code>: greater than, greater than or equal</li>
<li><code>$in</code>: member of. <code>value</code> must be an array of values</li>
<li><code>$ne</code>, <code>$nin</code>: not equal, not a member of</li>
<li><code>$stat</code>: checks whether the document posses the property <code>field</code>. <code>value</code> should be true or false</li>
<li><code>$regex</code>: checks whether a string is matched by the regular expression. Contrary to MongoDB, the use of
<code>$options</code> with <code>$regex</code> is not supported, because it doesn't give you more power than regex flags. Basic
queries are more readable so only use the <code>$regex</code> operator when you need to use another operator with it</li>
<li><code>$size</code>: if the referenced filed is an Array, matches on the size of the array</li>
<li><code>$elemMatch</code>: matches if at least one array element matches the sub-query entirely</li>
</ul>
</li>
<li>Logical operators: You can combine queries using logical operators:
<ul>
<li>For <code>$or</code> and <code>$and</code>, the syntax is <code>{ $op: [query1, query2, ...] }</code>.</li>
<li>For <code>$not</code>, the syntax is <code>{ $not: query }</code></li>
<li>For <code>$where</code>, the syntax is:</li>

// object is 'this'

modes at the time, except for <code>_id</code> which is by default always returned and

We need to compare with undefined as it will be used in indexes
In the case of objects and arrays, we deep-compare
If two objects dont have the same type, the (arbitrary) type hierarchy is: undefined, null, number, strings, boolean, dates, arrays, objects
