If you were careful in watching the code snippets above you will see something that we did not explain: the expressionbreak;. That expression is used to jump out of the loop, which means that it takes the command right after the loop, without executing the rest of it, but instead doing ...

In JavaScript, the array is also an object. So, the forin loop can be used to traverse through array elements. Like a string, the index is a key, and the array element is a value for the key.The below code prints the array index and its value in the output.Open Compiler <html> ...
