EC5 Spead Operator Sample Unused Variable

[WillCallahan]

The following ECMAScript 5 sample has an unused variable.

var params = [ "hello", true, 7 ];
var other = [ 1, 2 ].concat(params); // [ 1, 2, "hello", true, 7 ]
f.apply(undefined, [ 1, 2 ].concat(params)) === 9;

var str = "foo";
var chars = str.split(""); // [ "f", "o", "o" ]

The previously mentioned code should be changed to the following.

var params = [ "hello", true, 7 ];
var other = [ 1, 2 ].concat(params); // [ 1, 2, "hello", true, 7 ]
f.apply(undefined, other) === 9;

var str = "foo";
var chars = str.split(""); // [ "f", "o", "o" ]

Yes and no. Yes, one could use "other" here, of course. But that's no the point. The "var other ..." line is not there for the following line, but illustrates the spread operator just fine for itself in a stand-alone way. So, no, I will not reuse other as the "f.apply ...." line is a different usage of the spread operator and should be understood separately. Instead, I've now copied over the "f" definition from the Rest Operator example and added a blank line to make it more clear that the two Spread Operator examples are unrelated to each other.
