Javascript multiple “try”s

Question

We all know the basic escaping mechanism in JS:

try {
    ...
}
catch(err) {
    ..
}

I have a JSON data in which I want to check if a lead

Answer 1

You could nest your second try/catch block in the exception block of the first try/catch block as follows:

try {
    name = lead['Details']['Name']['Full'];
} catch(ex0) {      
  try {
      name = lead['Details']['Name']['First'] + " " + lead['Details']['Name']['Last'];
  } catch (ex1) {
      name = "No Name";
  }
}

This is valid syntax, and functionally equivalent to what you're requiring
