What is prepend?

Prepend is a method used in programming where a new element or item is added to the beginning of an existing list, array, or string. The new element is placed in the first position of the list, pushing all other items to a higher index. This method is commonly used in data manipulation, string concatenation, and other programming tasks where the order of elements is important. In programming languages such as Python, Ruby, and JavaScript, prepend is often achieved through built-in methods or functions. The opposite of prepend is append, where new data is added to the end of a list, array, or string.
