Lately, in templates, I've come across two different approaches:
myForm.controls.StartDate.value
and
myForm.get('StartDate').value
I initially thought that 'controls' was the recommended approach moving forward. However, when running ng build -prod, this causes a build error. Which method is considered best practice and won't cause issues during the build process?
After exploring the official Angular documentation on reactive forms, I discovered that they recommend using .get() on a FormGroup and .controls (in the template) on a FormArray. This distinction is important because a FormArray does not have named controls.
I also came across an article on handling forms in Angular 2 by Todd Motto, which mentions that there is no significant difference between using .get() and .controls, except that using .get() provides built-in error handling.
In my personal projects, I typically use .get() on FormGroup with success. It is challenging to determine which approach is superior nowadays. If .controls offers better IDE prompts, then it may be the preferred option - but without this feature, distinguishing between them can be difficult.
Furthermore, digging into the Angular source code repository, I found that .get() internally utilizes .find(), and .find() leverages .controls. Consequently, both methods should be safe to use, and either one should not cause issues in your production build.
