JavaScript Operator Precedence logic confuses me...

Question

The operator precedence table I can find is:

https://developer.mozilla.org/en/JavaScript/Reference/Operators/Operator_Precedence

according to the table, both '>>' and '*' are left-to-right associate, and '>>' have higher precedence, so I think a >> b * c should explain as (a >> b) * c however, my test in Firefox (using Firebug), tell me:

0x11 >> 1      ....    8
0x11 >> 1 * 2  ....    4

Which confuses me a lot, should it be 16 instead?

OK, I understand that we always should use parentheses when precedence is not clear, however there should be a rule or explain of what is happening?

Answer 1

According to the table you linked to, * has higher precedence (5) than >> (7); higher precedence is listed first in that table, though confusingly, lower numbers are used to indicate higher precedence.

Answer 2

According to the table you linked, multiplication has higher precedence (5) than bit-shifting (7).

From the top of the table:

The following table is ordered from highest (1) to lowest (17) precedence.

Answer 3

No, it says that * has higher precedence than >>. :)

Answer 4

if I look at that table, * has a higher precedence over >>.
