If this is the last thing they are left with, before doing the exercises and then their projects, I imagine that we would probably see more console.log
s than we would like?
getInformationAboutCats((err, data) => {
if (err) {
console.log('bad stuff happened. No cats')
} else {
// do stuff with data
}
})
Might be nice to have an else
statement in this?
function teachFac10(knowledgeOfErrors) {
try {
if (knowledgeOfErrors === 0) {
throw "How can I teach you? I know nothing"
}
}
catch(err) {
alert(err);
}
}
Just so they don't end up confusing try
with throw
(since both of these are new concepts), and see where, in this pattern, the success would come.
I know you have this in the next example, but maybe it's good to see it in the first one they come across too? Also because I'm sure "How can I teach you? I know nothing" isn't the only possible outcome ๐ฑ ?? ๐
Because we pull them up on it ๐
function getInformationAboutCats(callback) {
try {
asyncContactCatApi(function (err, data) {
if (err) {
throw (err);
} else {
// do something with the data
});
}
catch (err) {
alert('err')
}
}
}
getInformationAboutCats((err, data) => {
if (err) {
console.log('bad stuff happened. No cats')
} else {
// do stuff with data
}
})
