Answer 1

To do compound comparisons in JavaScript (or any other language syntactically derived from B), you don't do things like

(l>k>m)        // <=== Wrong

Instead, if you want to know if l is greater than k and k is greater than m, you use && (the logical "and" operator), like this:

(l>k && k>m)

Details:

Your original expression (l>k>m) breaks down into this:

((l>k)>m)

which means you'll get one of these:

(true>m)
// or
(false>m)

When comparing a boolean to a number, the boolean is coerced to a number, so that becomes in effect:

(1>m)
// or
(0>m)
