 ##  🔋 Included
 * `*rxIfList` - `*ngIf` for lists.
+* `runFn` - a pipe to run any function in the template without triggering change detection on every CD cycle.
 
 ### `rxIfList`
 A structural directive that works like `*ngIf` but for lists. It will only render the template if the list is not empty.

+#### `RunFnPipe`
+This pipe will run any function of your component and
+make use of Angular's memoization to prevent unnecessary
+re-evaluations which will result in less change detection cycles.
+
+Example using a pure function
+```
+@Component({
+  selector: 'my-component',
+  template: `
+    <div>
+      {{ sum | runFn:2:5 }}
+    </div>
+  `
+})
+export class MyComponent {
+  
+  // a pure function can easily be used like this:  {{ sum | runFn:2:5 }}
+  sum(a: number, b: number) {
+    return a + b;
+  }
+}
+```
+Example using im-pure functions (functions containing a `this`-reference
+```
+@Component({
+  selector: 'my-component',
+  template: `
+    <div>
+        {{ num | fn: value }}
+    </div>
+    <div>
+        {{ myfn | fn }}
+    </div>
+  `
+})
+export class MyComponent {
+  value = 10;
+    // 1a) a pure function can easily be used like this:  {{ sum | runFn:2:5 }}
+   num(a: number) {
+    return a;
+  }
+  
+   // 1b) wrapping in a arrow function will scope this correctly 
+   myfn = () => {
+    return this.value
+  };
+}
