}how to check if array is empty or not in javascript
if(typeof array != 'undefined' && array.length > 0){
// array has elements
}javascript check if array is not empty
if (array === undefined || array.length == 0) {
// array empty or does not exist
}javascript check if array is empty

}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
