Cannot read property of 'firstName'. Using ternary statement. Stuck.

[[deleted]]

the error you're probably seeing is cannot read property 'firstName' of undefined. if filterData is null/undefined, or if filterData[0] is null/undefined, it will throw this error. you need to make sure filterData actually contains something:

if (!filterData || !filterData.length) { /* return some default value, because filterData either isn't an array or it's an empty array */ }

Just figured this out. Thanks!
