try catch and finally code example

Example 1: javascript try

var someNumber = 1;
try {
  someNumber.replace("-",""); //You can't replace a int
} catch(err) {

Example 2: finally always after try catch

Finally block is ALWAYS executed AFTER try / catch Javascript blocks.

    try {
        data = JSON.parse(key)
    }
    catch (e) {
        // if the code errors, this bit of code will run
    }
    finally {
    
        return data
    }
