Documentation Request - Javascript

Question

Team,

Where can I find documentation regarding the left side of the equation of the below JavaScript Code:

var [a, b, c] = "10-11-12".split('-');

Result:
a = 10
b = 11
c = 12
// Note: this is used in Google Apps Script

Thanks!

Answer 1

This is called destructuring assignment

NOTE it's only available if your runtime is >= JavaScript 1.7

Answer 2

Mozilla Developer Network has some great documentation on the split method: https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/String/split
