Prepend is a term used in computer programming and data manipulation that refers to adding an element to the beginning of a list, string, or other data structure. For example, if you have a list of numbers and you want to add a new number at the start, you would prepend that number to the list. In many programming languages, such as Python or JavaScript, there are specific functions or methods designed to facilitate prepending. This operation is useful in various scenarios, such as organizing data or ensuring that certain elements are prioritized in processing or display.
