(function() {
var random_num = Math.floor(Math.random()*10) + 1;
var input_num = prompt("Guess the number between 1 and 10");
if (input_num < 1 || input_num > 10) {
alert('the input number is not between 1 and 10');
} else if (random_num == input_num) {
alert('Good Work');
} else {
alert('Not matched, the random number is: ' + random_num);
}
})();
But the IDE displays that "prompt" is not defined. Could someone help me explain why?
Assuming you're using JSHint in WebStorm, set Preferences > Languages & Frameworks > JavaScript > Code Quality Tools > JSHint > Environments > Browser to true

Update:
Also, as mentioned earlier, for good code you should use window.prompt, just so it's clear you're using the built in browser prompt rather than a custom function etc... (the same goes for alert, so use window.alert)
Finally, unrelated to the question, but something I noticed - it's good practice to use the === operator. There are a million articles online explaining why :)
Open your terminal or command prompt.
To clear the screen, type the command clear and press Enter.
Initialize a new npm project by running the command npm init -y in your terminal or command prompt. This will create a package.json file with default values.
Install the prompt-sync package by running the command npm install prompt-sync in your terminal or command prompt. This package allows synchronous user input.
At the top of your code file, add the following line to import the prompt-sync module and create a prompt object:
const prompt = require("prompt-sync")({ sigint: true });
Save your code file.
Run your code and check if the prompt functionality is working correctly.
windowproperty function. Ifwindowis not in the context of a browser, as @adeneo said,promptcannot exist.window.prompt(), it should be recognized.
