safe-object

safe-object

How many times have you seen Uncaught TypeError: Cannot read property 'something' of undefined?!

Well no more! safe-object to the rescue. Here is how to use it:

var so = require('safe-object');
 
var obj = { 
    user: {
        name: 'Jilles',
        demo: true
    }
}
 
// causes an error
if (obj.user.details.age) {
    console.log('oops');
}
 
// works, but ugly
if (obj.user && obj.user.details && obj.user.details.age) {
    console.log('meh');
}
 
// just skips the statement
if (so(obj, 'user.details.age')) {
    console.log('yaaay');
}
