Background: I program in other languages (primarily Python, C, C++ etc.), so I am well versed with OOP and the new keyword (especially, coming from a C++ background).
I am playing with a snippet of Javascript in a page, where I need to compare dates.
Version 1 (I think this is the way to go)
$('input#foo-create-submit').on('click', function(e){
let start_date = new Date($('#id_start_date').val());
let end_date = new Date($('#id_end_date').val());
let today = new Date();
/* custom logic follows ... */
});
Version 2 (This also seems to work - i.e. logical operation between date objects work ...)
$('input#foo-create-submit').on('click', function(e){
let start_date = Date($('#id_start_date').val());
let end_date = Date($('#id_end_date').val());
let today = Date();
/* custom logic follows ... */
});
Is the new keyword merely syntactic sugar? or is the JS VM doing some type conversion/coercion behind the scene (in which case I need to be aware of potential gotchas).
Which of the two is the canonical way to approach this kind of problem?
