- View SourceOk my question then is how would

if (

projectItemsIds.hasValue(

'123'

) &&

parseFloat(

"2"

) > 0 ||

parseFloat(

"-2"

) < 0

) {

where the 2nd and subsequent elements of the same level of logic is indented and offset from the alignment of the 1st element, be more readable then

if (

projectItemsIds.hasValue(

'123'

) &&

parseFloat(

"2"

) > 0 ||

parseFloat(

"-2"

) < 0

) {

where each element of the same level of logic is properly aligned?

Given a rational I can adapt to the advice given.

As always, Mr. Crockford, thank you for your time and expertise.

Anyway, I think it wants the expression to follow one space after the

operator, not be on the next line.

But why would you put the operator at the end of the line instead of at the

beginning?

if (

___projectItemsIds.hasValue('123')

______&& parseFloat("2") > 0

______|| parseFloat("-2") < 0

) {

Though this seems to me to need parentheses to make precedence clearer.

mostly it a semantics thing for me, in that my eye flows best if each element is on the same indent versus the same bool operator.

abc and

def or

ghi

versus

abc

and def

or ghi

and yes for the snippet above if it wasn't just a quick example that I threw in to test parenthesis would indeed be needed for clear precedence. - View Source--- In jslint_com@yahoogroups.com, "abyssoft@..." <abyssoft@...> wrote:

````````parseFloat("-2") < 0) {

But I should point out that I am not paid by the line.

In looking at your code, I see a possible error in depending on the precedence rules to make the interaction of && and || right. It is likely that JSLint will soon require more parentheses there.
