To complete this statement JavaScript has another statement called finally, which contains code that is executed regardless of the program flow, if the exception was handled or not, if there was an exception or if there wasn’t:
try {
//lines of code
} catch (e) {
} finally {
}You can use finally without a catch block, to serve as a way to clean up any resource you might have opened in the try block, like files or network requests:
try {
//lines of code
} finally {
