My code involved creating an array called dataArray of type dataRows, which is an interface.
dataArray: Array<dataRows>;In a function, I attempted to push a dataRows object into the array like this:
this.dataArray.push(row)But for some reason, I am seeing 'Cannot read property 'push' of undefined' in the console. Any ideas on why this might be happening?
If you're receiving the message
Cannot read property 'push' of undefineddataArray has not been initialized yet, leaving it as undefined - an empty object with no functions.
To fix this issue, make sure to start off by defining it as an empty array like so:
dataArray: Array<dataEntries> = [];
This will allow you to then utilize the .push function to add your row to it.
