2246 <h2 id="introduction">Introduction<a class="headerlink" href="#introduction" title="Permanent link">#</a></h2>
2247 <p>JavaScript offers only limited types of collections to hold and iterate over
2248 data. Despite the ongoing efforts in ES6 and newer, these new data structures
2249 and access methods, such as <code>for … of</code>, are not available in the still supported
2250 Internet Explorer 11.</p>
2251 <h2 id="dictionary"><code>Dictionary</code><a class="headerlink" href="#dictionary" title="Permanent link">#</a></h2>
2252 <p>Represents a simple key-value map, but unlike the use of plain objects, will
2253 always to guarantee to iterate over directly set values only.</p>
2254 <p><em>In supported browsers this will use a native <code>Map</code> internally, otherwise a plain object.</em></p>
2255 <h3 id="setkey-string-value-any"><code>set(key: string, value: any)</code><a class="headerlink" href="#setkey-string-value-any" title="Permanent link">#</a></h3>
2256 <p>Adds or updates an item using the provided key. Numeric keys will be converted
2257 into strings.</p>
2258 <h3 id="deletekey-string"><code>delete(key: string)</code><a class="headerlink" href="#deletekey-string" title="Permanent link">#</a></h3>
2259 <p>Removes an item from the collection.</p>
2260 <h3 id="haskey-string-boolean"><code>has(key: string): boolean</code><a class="headerlink" href="#haskey-string-boolean" title="Permanent link">#</a></h3>
2261 <p>Returns true if the key is contained in the collection.</p>
2262 <h3 id="getkey-string-any"><code>get(key: string): any</code><a class="headerlink" href="#getkey-string-any" title="Permanent link">#</a></h3>
2263 <p>Returns the value for the provided key, or <code>undefined</code> if the key was not found.
2264 Use <code>.has()</code> to check for key existence.</p>
2265 <h3 id="foreachcallback-value-any-key-string-void"><code>forEach(callback: (value: any, key: string) =&gt; void)</code><a class="headerlink" href="#foreachcallback-value-any-key-string-void" title="Permanent link">#</a></h3>
2266 <p>Iterates over all items in the collection in an arbitrary order and invokes the
2267 supplied callback with the value and the key.</p>
2268 <h3 id="size-number"><code>size: number</code><a class="headerlink" href="#size-number" title="Permanent link">#</a></h3>
2269 <p>This read-only property counts the number of items in the collection.</p>
2270 <h2 id="list"><code>List</code><a class="headerlink" href="#list" title="Permanent link">#</a></h2>
2271 <p>Represents a list of unique values.</p>

2273 <h3 id="addvalue-any"><code>add(value: any)</code><a class="headerlink" href="#addvalue-any" title="Permanent link">#</a></h3>
2274 <p>Adds a value to the list. If the value is already part of the list, this method
2275 will silently abort.</p>
2276 <h3 id="clear"><code>clear()</code><a class="headerlink" href="#clear" title="Permanent link">#</a></h3>
2277 <p>Resets the collection.</p>
2278 <h3 id="deletevalue-any-boolean"><code>delete(value: any): boolean</code><a class="headerlink" href="#deletevalue-any-boolean" title="Permanent link">#</a></h3>
2279 <p>Attempts to remove a value from the list, it returns true if the value has been
2280 part of the list.</p>
2281 <h3 id="foreachcallback-value-any-void"><code>forEach(callback: (value: any) =&gt; void)</code><a class="headerlink" href="#foreachcallback-value-any-void" title="Permanent link">#</a></h3>

2284 <h3 id="hasvalue-any-boolean"><code>has(value: any): boolean</code><a class="headerlink" href="#hasvalue-any-boolean" title="Permanent link">#</a></h3>
2285 <p>Returns true if the provided value is part of this list.</p>
2286 <h3 id="size-number_1"><code>size: number</code><a class="headerlink" href="#size-number_1" title="Permanent link">#</a></h3>

2290 <p class="admonition-title">This class uses a <code>WeakMap</code> internally, the keys are only weakly referenced and do not prevent garbage collection.</p>
2291 </div>
2292 <p>Represents a collection where any kind of objects, such as class instances or
2293 DOM elements, can be used as key. These keys are weakly referenced and will not
2294 prevent garbage collection from happening, but this also means that it is not
2295 possible to enumerate or iterate over the stored keys and values.</p>
2296 <p>This class is especially useful when you want to store additional data for
2297 objects that may get disposed on runtime, such as DOM elements. Using any regular
2298 data collections will cause the object to be referenced indefinitely, preventing
2299 the garbage collection from removing orphaned objects.</p>
2300 <h3 id="setkey-object-value-object"><code>set(key: Object, value: Object)</code><a class="headerlink" href="#setkey-object-value-object" title="Permanent link">#</a></h3>
2301 <p>Adds the key with the provided value to the map, if the key was already part
2302 of the collection, its value is overwritten.</p>
2303 <h3 id="deletekey-object"><code>delete(key: Object)</code><a class="headerlink" href="#deletekey-object" title="Permanent link">#</a></h3>
2304 <p>Attempts to remove a key from the collection. The method will abort silently if
2305 the key is not part of the collection.</p>
2306 <h3 id="haskey-object-boolean"><code>has(key: Object): boolean</code><a class="headerlink" href="#haskey-object-boolean" title="Permanent link">#</a></h3>
2307 <p>Returns true if there is a value for the provided key in this collection.</p>
2308 <h3 id="getkey-object-object-undefined"><code>get(key: Object): Object | undefined</code><a class="headerlink" href="#getkey-object-object-undefined" title="Permanent link">#</a></h3>
2309 <p>Retrieves the value of the provided key, or <code>undefined</code> if the key was not found.</p>
