It’s a script expression and it can be used in place of explicit property names or indexes. And it returns a list called a Filter expression. It selects all elements in an object or array list that match the stated or specified filter. It returns the list with the action of selecting the last n elements of the array. It returns the list with the action of selecting the first n elements of the array. If we have not mentioned this end in this expression it selects all the elements from start to end of the array list. It selects the array elements from the start index value and up to, but not the end index value. It denotes or layout the items inside the object. It selects all elements in an object or an array of elements, with a blind note of names or indexes. And one more asset of this property expression is it returns a list, even if just one property is found in this recursive search. It uses the Recursive Descent Parsing method to search for the specified property name recursively and returns an array of values with the property name specifically. It selects an array of elements with the specified index values and returns a list. It selects an n-th element from an array elements group and its index value is 0-based. It’s another representation of property expression with the bracket notation. It selects the selective property in a parent object. It represents the root object or array of elements and it would be the neglectable expression.
