}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
}check row empty array javascript
if(array && array.length){
// not empty
} else {
// empty
}javascript cehck if array is empty
if (array === undefined || array.length == 0) {
// array empty or does not exist
