I am really at the beginning with JavaScript and I am trying to assign a value of my object field. The value is coming from another object, but that value must be modified. It crashes if the value is null, so I need a try-catch block but I don’t know how to do it.
var marker = new google.maps.Marker({ ... this_one: parseInt(clients[i].fields.SomeFieldOfMyObject.replace('.', '')), ... });
I want to convert some values that might be like “54.2” to (int) 54. But there are objects that have SomeFieldOfMyObject null and my application is crashing.
I am looking for something like:
this_one: function() { try: return parseInt(clients[i].fields.SomeFieldOfMyObject.replace('.', '')) catch: return 0 }

You can use an IIFE to run a function, where you can test the result of parsing the value and use try/catch
.
this_one: (function() { try { let val = parseInt(clients[i].fields.SomeFieldOfMyObject.replace('.', '')); return isNaN(val) ? 0 : val; } catch (e) { return 0; } })()
