So when do we useforand whenwhile? If the number of iterations is known use theforloop. If you want to loop until a certain condition is met use thewhileloop. for in # Afor-inloop iterates through the properties of an object and executes the loop's body once for each enumerable pro...
Loops are used to execute the same block of code again and again, as long as a certain condition is met. The basic idea behind a loop is to automate the repetitive tasks within a program to save the time and effort. JavaScript now supports five different types of loops:...
Loops perform an operation (i.e., a chunk of work) a number of times, usually once for every item in an array or list, or to simply repeat an operation until a certain condition is met. JavaScript in particular has quite a few different types of loops. I haven’t even used all of...
Each has its own specific purpose but the idea is the same — keep repeating code so long as some condition is being met. In this chapter, we start off by exploring all the nitty gritty details of the for loop, followed by those of while in the next chapter. Let's begin. What is ...
Now we repeat the 2, 3 phases until the condition is not met and the for loop is left. In our case, when the counter is equal to the size of the array, the for loop stops executing. JavaScript array loop with while statement
The while loop continues until the condition is met. if (min % num1 == 0 && min % num2 == 0)The LCM of two numbers can also be found using the formula:LCM = (num1*num2) / HCFTo learn about how to find the HCF, visit the JavaScript program to find HCF.Example...
At the core level, both for and while continue iterating only if the given condition is met i.e. it evaluates down to true. However, both are used for different purposes. Difference between for and while for, as we know, is more commonly seen when iteration is to be done on a given...
As mentioned,setTimeoutis great for firing a one-off action after a delay, but it’s also possible to usesetTimeout(or its cousinsetInterval) to keep JavaScript waiting until a condition is met. For example, here’s how you might usesetTimeoutto wait for a certain element to appear on...
Use the break Keyword to Exit for Loop in JavaScript Use the return Keyword to Exit for Loop in JavaScript The for loop executes code statements repeatedly until the specified condition is met. We need to exit our loop and break the continuous execution most of the time. In this article...
When the condition isn’t met, the loop finishes and the code continues with the first next command, in this case, the alert method. The third part is the command to increment the counter. You can increment the counter by 1 (like in this case), or by any other number....
