Troubleshooting issue: Angular Typescript object array filter functionality malfunctioning

I am currently attempting to filter an array of objects based on a specific value. Interestingly, out of the console.log outputs provided below, only the first one is yielding the expected result:

console.log('log1: ', sf);
console.log('log2: ', sf.filter(f => true));
console.log('log3: ', sf.filter(f => f.Specification.FormSelector === 'app-g-form'));
console.log('log4: ', sf.findIndex(f => f.Specification.FormSelector.includes('app-g-form')));

The outcomes for the above are as follows:

Upon analyzing log2, log3, and log4, my anticipation was that the console output would align with that of log1. The display from log1 affirms that the content within sf does indeed hold valid data.

Answer №1

Appreciate the feedback provided.

I believe I have successfully resolved the issue. Instead of setting parts of the array with:

const sf1: GSubForm = {Specification: this.detailSpecification};
this.specification.SubForms.push(sf1);

The code above was originally located within an observable that retrieved data from an API. Upon setting the data, I then initialized the SubForms array. However, by relocating this code outside of the observable and directly into ngOnInit(){}, the functionality started working as intended.

It's unclear why one method worked while the other did not, but I am pleased to see progress being made.
