问题 I have a node.js app and I need to implement statistics for it. I have two ways: writing into the console.log and then capturing it using some tool (AWS CloudWatch Metrics) or calling AWS API and send stats over the Internet. The thing is: Writing anything into the console requires resources and time . But calling an API to publish my stats also requires resources and time . I am curious which way is more effective? Which way I am using less CPU resources? 来源： https://stackoverflow.com

问题 I'm getting this on Azure CI when running Cypress in a docker container in a release pipeline. I'm guessing it could be because of some setting in Cypress, docker, NodeJS, or the CI itself. ![ ]1 I tried the NO_COLOR=1 Cypress option in the pipeline, but it didn't seem to have an effect. 回答1: The environment variables set in the pipeline will not be active inside the Docker container. The Docker container has its own set of environment variables. I believe you will be able to resolve your

问题 How My Question is Different From Others I am using ES6 syntax. The other questions I looked at uses ES5 syntax. The Question Why does alert(); run before console.log(); ?

My Code console.log("Hello!"); alert("Hi!"); 回答1: console.log("Hello!"); setTimeout(() => alert("Hi!"), 0); Basically: console.log() is being called first, technically. † However, the browser actually repainting itself or the console updating also takes

问题 In Python: print [1,2], '\n', [3,4] would print [1,2] [3,4] In Javascript: console.log([1,2],'\n',[3,4]) prints [1,2] '\n' [3,4] What is the equivalent Javascript statement to the above Python print ? 回答1: You are sending three arguments to console.log console.log([1,2],'\n',[3,4]) Because the first argument, [1,2] doesn't contain formatting elements (e.g. %d ), each argument is passed through util.inspect(). util.inspect is returning the string representation of '\n' which is not what you

问题 In the console of Chrome you can write pretty nice stuff these days. Checkout this link. I've also made a screenshot: As you can see in the screenshot too, the file name / line number ( VM298:4 ) is written at the right.

You will need to use setTimeout with a console.log.bind : setTimeout (console.log.bind (console,

问题 To my knowledge, console methods are bound in most if not all modern JS engines. var log = console.log; log('foo'); window.addEventListener('load', console.log); // or any other API that accepts callbacks will result in proper console output, at least in up-to-date Edge, Firefox and Chrome/Node.js versions, so it's relatively safe to rely on this behaviour in development environment. Unfortunately, Can I use and MDN don't cover this and potentially contain unverified information. What are

问题 On the node.js interpreter:- console.log("A newline character is written like \"\\ n \"."); //output is:- // A newline character is written like "\ n ". But when you simply enter this in the node.js interpreter:- "A newline character is written like \"\\ n \"." // it prints out:- //'A newline character is written like "\\ n ".' Does anybody now why this happened? Just curious to know more about node.js Thanks in advance for your answer. 回答1: When logging a string, it gets fully parsed and

问题 Any player can easily cheat on this game by changing the amount of cupcakes through the browser console. I wanted to know if there was a way to prevent the user from doing so. This is also posted on github. var numberOfCupcakesDisplay = document.getElementById("numberOfCupcakes"); var cupcake = document.getElementById("cupcake"); function updateValues() { numberOfCupcakesDisplay.innerHTML = amountOfCupcakes.toString(); //displays number of cupcakes to screen document.getElementById(
