process . stdout . write 和 console.log in Node.js
的区别
原文:https://www . geesforgeks . org/process-stdout-write-and-console-log-in-node-js/
NodeJS 中的 process.stdout.write 和 console.log 都具有在控制台上显示消息的基本功能。基本上 console.log 实现 process.stdout.write 而 process.stdout.write 是一个缓冲区/流，会直接输出到我们的控制台。
process . stdout . write 和 console.log in Node.js 的区别是:
| Sl 没有。 | **流程。stdout** | **控制台。日志** | | --- | --- | --- | | one | It will print information continuously along with the data being retrieved without adding new lines. | Information obtained during printing is retrieved and new lines are added. | | Two | Use **process.stdout** for the variable of the display object. | Use **console.log** to display many unreadable characters for a variable. | | three | It takes only strings as arguments. Any other data type passed as a parameter will throw a type error. | It takes any JavaScript data type. | | four | If we don't put the dash at the end, we will get a weird character after our string. | We don't need a line feed here, because it's already formatted, and the weird character really disappeared. | | five | It can be used to print patterns because it does not add new lines. | We use it when we want to print the results on a new line. | | six | 我们不能写多个字符串。例如: `process.stdout.write("Hello","World");` 输出:这会给出一个类型错误。 | 我们可以写多个字符串。例如: `console.log("Hello", "World");` 输出:这会在控制台打印 Hello World。 | | seven | 我们不能搞联想。例如: `process.stdout.write("Hello %s", "All");` 输出:这会给出一个类型错误。 | 我们可以做联想。例如: `console.log("Hello %s", "All");` 输出:这将在控制台打印 Hello All。 |示例:下面的示例是展示如何使用 process.stdout.write
java 描述语言
<script>
// For process.std.out
process.stdout.write("Hello");
process.stdout.write("World");
process.stdout.write("!!!");
</script>
输出:
HelloWorld!!!
示例:下面的示例是展示如何使用控制台
java 描述语言
<script>
// For console.log
console.log("Hello");
console.log("World");
console.log("!!!");
</script>
输出:
Hello
World
!!!
