Is there a javascript equivalent to unpack sequences like in python?

Is there a javascript equivalent to unpack sequences like in开发者_如何学运维 python?

a, b = (1, 2)

[a, b] = [1, 2]

Update:

Browser compatibility matrix:

• Firefox: all versions
• Opera: 9.x only
• Chrome: 49 and higher
• MSIE: no
• EdgeHTML: 14 (Browser version 31, released Feb. 2016)
• Safari: 7.1 (8 for Safari Mobile)

There isn't. JavaScript doesn't have such syntax sugar.

An object cannot contain a reference to an integer, only its value. So I can't see any way to do what you ask in javascript.
