There we exited out of the switch statement once the condition is satisfied. We have seen the JavaScript break statement in the switch part. To handle such situations JavaScript has a break and continue statements. There are many use cases when we have to exit a loop, with it going through the full iterations.Īlso, there are situations where you need to skip some of the iterations. JavaScript provides control to exit out of loops and also switch statements.
There we exited out of the switch statement once the condition is satisfied.Now, let look at an example where we can break from a for loop.var num = 10 for(var counter=0 counter < 100 counter++) //Outer loop i - 0 //Inner loop j - 1 //Inner loop j - 3 //Outer loop i - 1 //Inner loop j - 1 //Inner loop j - 3 //Outer loop i - 2 //Inner loop j - 1 //Inner loop j - 3 //Outer loop i - 3 //Inner loop j - 1 //Inner loop j - 3 //Outer loop i - 4As in the above example, whenever the inner loop of j encounters 0, 2, 4 the condition j%2 = 0 becomes true and the continue will run to the label innerLabel.Similarly, when the condition i = 4 is true, we get a break from both inner and outer loop and go to the label outerLabel. There are many use cases when we have to exit a loop, with it going through the full iterations.Also, there are situations where you need to skip some of the iterations.To handle such situations JavaScript has a break and continue statements.break statementWe have seen the JavaScript break statement in the switch part. One point to remember is that functions in javascript always return something even if not stated explicitly, with undefined being the default return value.JavaScript Tutorial By KnowledgeHut JavaScript provides control to exit out of loops and also switch statements. There are 3 major javascript exit functions namely, return, break, or throw. So, how do we exit functions in javascript? In languages such as PHP and C, an exit() function exists which can be used to exit the loop in such cases. We may often come across the situation of wanting to exit a function early, for example in the case of building functions with multiple conditions, we may want to exit the loop if a specific condition is satisfied. However, If you are just looking for the code, you can skip to the code section below. If you are new to programming or JavaScript, we recommend you read through the entire article. In this article, we are going to see the different types of javascript exit functions.
