1. In the design section, add a headline component
2. Open the bindings drawer of the headline component, switch to JavaScript, and type

• one user noted their tab crashing simply when typing while

Expected behavior
Builder should either handle a while-loop, or totally prevent it.

BUDI-9005 Any JS that uses "while" immedately crashes the tab

We'll do our best to try and think of a solution to this, but fundamentally it's just that if you write an endless loop in JavaScript, it will hang the tab. One solution might just be to reduce the frequency of live evaluation, so that it doesn't run immediately but instead only when pressing a button or something. It's definitely annoying if you want to use a while loop in a binding, since you'll almost always end up writing valid syntax that's an endless loop before you add the code to let it terminate.
