value.add(value[, value, ...]) → value
time.add(number[, number, ...]) → time
Sum two or more numbers, or concatenate two or more strings or arrays.
The add command can be called in either prefix or infix form; both forms are equivalent. Note that ReQL will not perform type coercion. You cannot, for example, add a string and a number together.
Example: It’s as easy as 2 + 2 = 4.
> r.expr(2).add(2).run(conn, callback)
// result passed to callback
4
Example: Concatenate strings.
> r.expr("foo").add("bar", "baz").run(conn, callback)
// result passed to callback
"foobarbaz"
Example: Concatenate arrays.
> r.expr(["foo", "bar"]).add(["buzz"]).run(conn, callback)
// result passed to callback
[ "foo", "bar", "buzz" ]
Example: Create a date one year from now.
r.now().add(365*24*60*60).run(conn, callback)
Example: Use args with add to sum multiple values.
> vals = [10, 20, 30];
> r.add(r.args(vals)).run(conn, callback);
// result passed to callback
60
Example: Concatenate an array of strings with args.
> vals = ['foo', 'bar', 'buzz'];
> r.add(r.args(vals)).run(conn, callback);
// result passed to callback
"foobarbuzz"
