I am trying to replace legend item names in a Carto VL map. Using an example from the documentation which describes how to rename the "CARTO_VL_OTHERS" category, I was able to rename one of my legend items. For example:

colorLegendList +=
 `<li><span class="point-mark" style="background-color:$color;border: 1px solid black;"></span> 
 <span>$legend.key.replace("EN", "Endangered")</span></li>n`;

Which results in:

How would I rename the rest of the legend items as:

• VU - Vulnerable


• CR - Critically Endangered


• LT - Least Threatened

You could create an Object before layer.on('loaded'... with the legend keys you want to use for this dataset, for example:

 const LEGEND_KEYS = 
 LT: 'Least Threatened',
 VU: 'Vulnerable',
 CR: 'Critically Endangered',
 EN: 'Endangered'
 

And then, when updating the legend:

colorLegendList +=
 `<li><span class="point-mark" style="background-color:$color;border: 1px solid black;"></span> 
 <span>$LEGEND_KEYS[legend.key]</span></li>n`;
