The most fundamental of the conditional statements is theifstatement. Anifstatement will evaluate whether a statement is true or false, and only run if the statement returnstrue. The code block will be ignored in the case of afalseresult, and the program will skip to the next section. Anif...
In addition toif...else, JavaScript has a feature known as aswitchstatement.switchis a type of conditional statement that will evaluate an expression against multiple possible cases and execute one or more blocks of code based on matching cases. Theswitchstatement is closely related to a conditio...
document.write("Anything you want to print"); number++; if(number < 100) goto start_position; This is not a code. Just an example where you want to use goto statement. Now I will show you how to achieve this in JavaScript var number = 0; start_position: while(true) { document.wri...
Unlike all the other constructs in JavaScript, theforstatement uses semicolons rather than commas to separate its arguments. This is the same as the syntax used in C, C++, and Java. Here’s an example of aforloop that counts from 1 to 10, stepping one digit at a time. At each itera...
JavaScript is traditionally single-threaded, even with multi-cores. We can get it to run tasks only on a single thread called the main thread. Such synchronous behavior is a limiting factor in the multi-threads but helps the user write codes without worrying about concurrency problems. ...
How can I add an if else conditional statement to this function? How do I make an alert() that gives the result of a if else statement using external JS How do I write an if/else statement inside a function that tells me if a number is evenly divisible by 2 (in javascript) Ho...
Otherwise, it throws a custom alert as written in the else statement in the script. Since we have simulated an alert in the script, we need to use the accept method in Selenium to resolve it. See the demonstration below. The last step is to end the test and quit the driver instance....

Ideally, we want the quiz’s questions and answers to be in our JavaScript code and have our script automatically generate the quiz app. That way, we won’t need to write a lot of repetitive markup, and we can add and remove questions easily....
So when you call a function, it gets pushed to the stack. If that function contains Web API call, JavaScript will delegate control of it to the Web API with a callback function and move to the next lines until function returns something. Once function hits return statement, that function ...
