I found next form of new operator in the less documentation.
var parser = new (less.Parser) ({
pathes [
'.',
'./css'
],
filename: 'style.less'
});
What the differences from the usual form?
var parser = new less.Parser({
patches [
'.',
'./css'
],
filename: 'style.less'
});
Can it be combined with .apply method?
There's no difference between
var parser = new (less.Parser) (...);
and
var parser = new less.Parser (...);
The parens around less.Parser are entirely superfluous.
Can it be combined with .apply method?
It's difficult to use a function designed to be called via new (a "constructor function") via apply, because new does a lot of things. (This is true of both forms of the above, since — again — they're the same thing.) I talk about using apply with constructor functions more in this other answer here on Stack Overflow.
