console.log([data][, ...args])


    使用换行符打印到 stdout。 可以传入多个参数,其中第一个用作主要消息,所有其他参数用作类似于 printf(3) 的替换值(所有参数都传给 util.format())。

    Prints to stdout with newline. Multiple arguments can be passed, with the first used as the primary message and all additional used as substitution values similar to printf(3) (the arguments are all passed to util.format()).

    const count = 5;
    console.log('count: %d', count);
    // Prints: count: 5, to stdout
    console.log('count:', count);
    // Prints: count: 5, to stdout

    See util.format() for more information.
