With this, we can effectively make use of the JavaScript engine. Ziege chinesisches Sternzeichen, Persönlichkeit, Eigenschaften, Element, Kompatibilität. Later, we can come back and show the API call results as soon as we get the response back from the server. During that time, we will try to complete other tasks.
This will make that function asynchronous, and then with the help of await, we will wait for some time. Instead of waiting for the response, we can add the async keyword before that function that is making the API call which will return a Promise object. Let’s say we are performing an API call then, it might take some time to get the response back from the server. But there are times when we want to perform some operations that take some time to execute, and during this time, keeping the user waiting for the results is not a good idea.
Because of this, JavaScript code can only be executed line by line. Implement the sleep() Function With Promise, async and await in JavaScriptĮveryone is aware that the JavaScript programming language is a single-threaded language which means it has only one call stack and one heap stack.Implement a sleep() Function Without Promise, async and await in JavaScript.Syntax of JavaScript Sleep Function: sleep(delayTime in milliseconds). Here, we can observe the asynchronous behavior of JavaScript as it does not waits for anything while execution and continues its work further. Refer to the URL to get the data referred for displaying. then(sampleJson => console.log(ssage)) console.log("Hello!") Īs we can see in ruby, firstly the data from the URL is fetched, and then the message property value “Not Found” is displayed and after that the static message saying “Hey! Let us have a look at message.” is displayed while in case of JavaScript, firstly the request for getting the URL data is sent and JavaScript does not wait till the response comes, instead it executes the second statement displaying “Hello” on console and when the response of the sent request arrives, it displays the message value saying “Not Found”. then(sampleResponse => sampleResponse.json()) Where “Not Found” is the message string stored in the issues section on the mentioned github url.
Puts "Hey!Let us have a look on message." SampleResponse = JSON.parse(Net::HTTP.get(sampleUri)) puts sampleResponse SampleUrl = '' sampleUri = URI(sampleUrl)
