Hey guys, I've been searching for answers on this issue but haven't found a solution yet. I'm delving into Angular and came across this code snippet that is meant to count and split the letters within a given word. However, I'm encountering an issue where the curly braces are appearing as if they were ordinary text in HTML. Any ideas on what could be going wrong here?

Answer №1

observation made about the absence of module initialization for 'app'. To rectify this, one can simply use <div ng-app>. Alternatively, outlining the module can be beneficial:

angular.module("app", []);

UPDATE

A concern raised by @Peter_Fretter highlights the need to address duplicates within the ng-repeat. This issue can be resolved by employing track by $index:

<div ng-repeat="item in 'somewords'.split('') track by $index">
    {{$index + 1}}. {{item}}
</div>

Feel free to check out this jsfiddle

Answer №2

If you're encountering issues with duplicates, utilizing the track by feature can help resolve them.

<div ng-repeat="item in 'uniquewords'.split('') track by $index">
        {{$index + 1}}. {{item}}
</div>
