Terser keep (don't mangle) a specific function name

Question

Is there a way to not mangle only one function name? A comment in the code would be easiest, but I guess this could be done by specifying a custom "nameCache"? But I don't know how that works.

Answer 1

I couldn't figure this out, but I already had the function name so I stored the function name on the webpage in an attribute that I could find later with JavaScript.eg

 function bob() { console.log('hello'); } document.querySelector('#myid').setAttribute('data-function-name', bob.name);

 <span id="myid">for example make this style="display:none;"</span>
