Console.log有没有办法命名发送变量？ [英] Console.log is there a way to name sent variables?

问题描述

将项目发送到console.log时有没有办法命名它们？类似于visual studio中的watch

When sending items to console.log is there a way to name them? Similar to "watch" in visual studio

例如我们有一个 var counter = 1;
所以在控制台日志中它显示为：

for example we have a var counter=1; so that in the console log it appears as:

counter 1
counter 2

依旧......

推荐答案

不是直接的，但你可以在输出时命名它们。

Not directly, but you can just name them when you output them.

console.log （和 .error ， .info ， .warn ）让你同时传递任意数量的值，所以这样做是非常容易的：

console.log (and .error, .info, and .warn) let you pass any number of values at the same time, so it's super easy to just do something like this:

console.log('counter', counter);

输出如下：

counter 1

let counter = 0;

for (let i = 0; i < 5; i++) {
  counter++;
  console.log('counter', counter);
}
