I was playing around in jsfiddle.net and I'm curious as to why this returns true?
if(0 < 5 < 3) {
alert("True");
}
So does this:
if(0 < 5 < 2) {
alert("True");
}
But this doesn't:
if(0 < 5 < 1) {
alert("True");
}
Is this quirk ever useful?
Order of operations causes (0 < 5 < 3)
to be interpreted in javascript as ((0 < 5) < 3)
which produces (true < 3)
and true is counted as 1, causing it to return true.
This is also why (0 < 5 < 1)
returns false, (0 < 5)
returns true, which is interpreted as 1
, resulting in (1 < 1)
.
