Spread and Rest Operators in JavaScript #javascript #DSA #javascriptinterview

n JavaScript, the spread and rest operators are both represented by three dots (...), but they serve different purposes.

Spread Operator (...):
- The spread operator allows an iterable (like an array or a string) to be expanded into individual elements. It is used to split up array elements or object properties.
- When used with arrays, it can be used to copy an array, concatenate arrays, or pass elements of an array as arguments to a function.
- With objects, it can be used to create shallow copies of objects, merge objects, or clone objects with new properties.

Rest Parameter (...):
- The rest parameter syntax allows you to represent an indefinite number of arguments as an array.
- It is used in function definitions to capture multiple arguments into a single array parameter.
- The rest parameter must be the last parameter in a function.
