Example #1Ĭlick the button below to select the second and the third elements from the array and print. Similarly, if the end parameter is not defined then the slice() method will extract up to end-1 which means it will use the length or size of the array for end parameter. We should also note that in the slice() method if the start parameter is not defined then slicing begins from the index 0 of the array and therefore this start parameter identifies the zero-based index of the array. This method returns a new array that contains the selected elements of the array. end: this parameter is used to define the index of an array at where the function should stop extracting the elements from the array.start: this argument is used to define the index of an array from where the function should start selecting the elements of an array.System Images: android-28 | Intel x86 Atom_64, android-28 | Google APIs Intel x86 Atom, android-28 | Google APIs Intel x86 Atom_64Įxport const createAlert = (title, msg) => Įxpect the alert to show on the device, but instead the exception is caught by Sentry.

I’m attempting to create an alert when the user encounters an error, but instead a JS error is thrown. The Alert function no longer works in my project.
