Use label statement with break keyword in loops Statement // it can be loop, block of code, etc. Users can follow the syntax for the label as follow. Label − It can be any string to give a name or label to the block of code.īreak − It is used to terminate the execution of the block of code, loop, or switch statement. Here are the basic definitions of the label and break keyword. In this tutorial, we will learn to use the label and break statement with the loops, and block of codes. It stops the execution of the code in the middle. We can use the break keyword with the label statement.
The label is a unique string we can use to give the identity to the block of code, loops, switch cases, etc., in JavaScript. The label and break statement are not new in JavaScript, and many of you are familiar with both. Then, introduce an if statement and terminate the loop from running with a cap limit of 51.This tutorial will teach us to use a label with a break statement in JavaScript. Use the break statement to work with the numbers labeled as i. Use the break statement for a simple list with three strings, such as “zebra,” “giraffe,” and “gazelle.” Using the for loop, terminate the command to show only the first two strings. When using every and some approaches and arrays, you don’t have a way to benefit from the loop repeatability. Not only is this approach the slickest and most readable, it also does allow performing await operations within it. However, when you’re using the for…of loop and the break statement, you can make the most of its functionality. var agesOfGuests = Īlert( `Alcohol menu is available for guest number $Īs you can see, in all three examples, the output is the same. Depending on the person's age, we will be able to offer or refuse alcohol. To demonstrate the break we will take into account the age of guests, that is we will form an array of ages. Let us have some information about each guest, including their age. Imagine, we have a group of people invited to an event.
In general, this operator is not required. Syntax looks as follows: break Īn identifier associated with the label of the break statement is required if the statement is not a loop or switch. This could be useful when it is necessary to interrupt the cycle. The program continues running with the following statement. The break statement terminates the current loop or other operator.
