You have two methods: one method takes long time to run and the other completes in short time. You execute the long method first and after that you execute the short method. Which one will complete first. There is no setTimeout involved.

4 risposte

My answer: The long method finishes first and then short method executes and completes. Expected answer: The short method returns first! Meno

the short method returns first! is the right answer since two methods will run parallel. As javascript is async events handling. You may right if had quested him is the methods run in sequence. Meno

@Anonymous. It looks like you have not read the question well. It says that there is no setTimeout[) involved. If you have read the question, I have some questions for the answer that you provided. 1. Is asynchronous same as multithreading? I remember reading that JavaScript is single-threaded. 2. Suppose the short method depends on some value modified by the long method. As you said, lets suppose that the short method returns first even though it is next to the long method in sequence. In this case, how do you manage your program? Meno

What is the output of below program. var a = [1,2,3,4] for (var i=0; i<a.length; i++){ setTimeout(function(){ console.log(i) },1000) } ( My Ans : it will print 4 5 times as it will store the latest reference) Next They asked me : How can i print 1,2,3,4 by changing some code in above example

3 risposte

Some Correction : It will print 4 times "4". Fix: just use "let"(block scope) rather than "var" It should be : console.log(a[i]) to print (1,2,3,4) Meno

Yes, ofcourse, it'll print 4 times 4 (not 5 times). Another way could be: using closure function. var a = [1,2,3,4] for (var i=0; i Meno

My Answer : var a =[1,2,3,4] for (var i=0; i
