Errors

Define the term "Error" as it relates to JavaScript.
Read a "Stack Trace" to extract the following information:
- The line of code where the error occurred.
- The type of error that occurred.
- What path the code traveled to get to that line.
Use a try/catch block to handle expected errors.
Throw a custom error.

var someObject = {
    property = 7;
}

console.log(undef);

var sensibleArray =
new Array(-1);

var num = 4;
num();

Impossible!

Unreasonable!

requests

It terminates the whole program...

try {
} catch(error){
}
