An array method refers to a built-in function or operation that can be performed on an array data structure to manipulate its elements or retrieve information. Common array methods include operations like map, filter, reduce, and forEach, which allow developers to process and transform data efficiently. These methods are widely used in programming languages such as JavaScript, Python, and Java to enhance code readability and reduce complexity.

Is array list a value type or reference type?

Program to insert an element in array at beginning?
Answer: Use the unshift() Method You can use the unshift() method to easily add new elements or values at the beginning of an array in JavaScript. This method is a counterpart of the push() method, which adds the elements at the end of an array. However, both method returns the new length of the array To learn more about data science please visit- Learnbay.co
How are entire arrays passed from one method to another?
In some programming languages, like C, you can pass the new method (or function) an address pointer to the first element in the array. As long as you don't leave the scope of the method the array was created in, the array will remain valid. In other languages that don't support memory addresses, like FORTRAN, it must be done by making the array global.
