try / catch

• Sometimes operations fail
• It would be nice to be able to handle errors gracefully
• Errors immediately exit the current function and keep bubbling up until something catches them
• try / catch in JavaScript lets you do this
• You can catch an error and handle it

try {
    someSketchyFunction(); // This function might fail
} catch (e) {
    console.error(e.message) // What to do with the failure
}
