Front-End Javascript question (no espocrm)

[item]

Hi,
what do that mean ?

attributes['assignedUserId'] = [model.get('assignedUserId')]
attributes['assignedUserName'] = [model.get('assignedUserName')]​ 

Ok : atttibutes is a array

Not understand = [ .... ] , why model.get('assignedUserId') is under 2 bracket ?
and why not ; at the end of line ?

Why not :
attributes['assignedUserId'] = model.get('assignedUserId') \*with at end*\ ;

Just for my knowledge.

This is the same as:

const list = [];
list.push(model.get('assignedUserId'));
attributes['assignedUserId'] = list;

But the code snipped does not make sense in the Espo context. As assignedUserId is always string or null, not an array.

Semicolon is not mandatory is javascript.
