In TypeScript, there is a chance that the object may be undefined, so I make use of an if

I'm encountering an issue with this code snippet. I have a check in place to ensure that the value of 'startups[i].logo' is not undefined, however I am still receiving an error stating that it may be undefined. Can anyone provide insight as to why this error is occurring?

  for (let i = 0; i < startups.length; i++) {
    let startup = startups[i];
    if (startups[i] && startups[i].logo && startups[i].logo.location) {
      aStartup.push({
        objectID: startups[i].id,
        logo: startups[i].logo.location,
      });
      batchCount ++;
    }
typescript

Answer №1

Assigning Nullable Values to Local Variables:

for (let i = 0; i < startups.length; i++) {
  const startup = startups[i];
  const logo = startup.logo;

  if (startup && logo && logo.location) {
    aStartup.push({
      objectID: startup.id,
      logo: logo.location
    });

    batchCount ++;
  }
}

This approach is beneficial as it ensures TypeScript recognizes all potential nullable conditions have been addressed within this segment of code.
