import pytablewriter as ptw


def main():
    writer = ptw.JavaScriptTableWriter(
        table_name="js_variable",
        headers=["int", "float", "str", "bool", "mix", "time"],
        value_matrix=[
            [0, 0.1, "hoge", True, 0, "2017-01-01 03:04:05+0900"],
            [2, "-2.23", "foo", False, None, "2017-12-23 45:01:23+0900"],
            [3, 0, "bar", "true", "inf", "2017-03-03 33:44:55+0900"],
            [-10, -9.9, "", "FALSE", "nan", "2017-01-01 00:00:00+0900"],
        ],
    )

    writer.write_table()


if __name__ == "__main__":
    main()
Output
const js_variable = [
    ["int", "float", "str", "bool", "mix", "time"],
    [0, 0.1, "hoge", true, 0, "2017-01-01 03:04:05+0900"],
    [2, -2.23, "foo", false, null, "2017-12-23 45:01:23+0900"],
    [3, 0, "bar", true, Infinity, "2017-03-03 33:44:55+0900"],
    [-10, -9.9, "", "FALSE", NaN, "2017-01-01 00:00:00+0900"]
