Populating timetoday columns with vars

Why does this work:

table.setCell(0,0,[18,12,31]);

and this doesn't

strTime="18:12:31";
time = strTime.split(":");
table.setCell(0,0,time);


the column has been defined by

table.addColumn('timeofday','Time');

When you do a

strTime.split(":");

the result is an

Array [ "18", "12", "31" ]

which contains strings, not integers. Yet, the `timeofday` type [requires an array of four numbers][1]:

> If the column type is 'timeofday', the value is an array of four
> numbers: [hour, minute, second, milliseconds].

To obtain an array of `Number`s, you could use

strTime.split(":").map(Number)

which applies the `Number`-function to each string element. This returns a Number object. The `map` applies it recursively to each element of the array.
