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" Couldn't find what you were looking for?
