}check array empty or not in javascript
// To safely test if the array referenced by variable “array” isn’t empty:
if (array && array.length) {
// not empty
} else {
// empty
}
// Note that if “array” is assigned to some other object that isn’t an array, the code will still execute the “else” part.
// A possible improvement to check that the object is specifically an empty array might be this:
if (array && array.constructor === Array && array.length === 0) {
// strictly an empty array
} else {
// either null, or not an array or not an empty array
}what is the value if arrary in empty
int baz [5] = { };
//When an initialization of values is provided for an array, C++ allows the possibility of leaving the square brackets empty []. In this case, the compiler will assume automatically a size for the array that matches the number of values included between the braces {}:Copyright © 2021 Codeinu
