A tuple is similar to a pair. Each pair always has exactly two members; while each tuple can have any number of members.
A tuple is most useful when we want to combine some data into a single object but do not want to bother to define a data structure to represent those data. A tuple can be thought of as a “quick and dirty” data structure.
C/Go/Kotlin has no tuple yet.
JavaScript doesn’t have tuples. But with array destructuring, we can pretend it does! In JavaScript, arrays already allow multiple types to be grouped. A “tuple” in JavaScript will simply be an array of known length, whose values are of a known type, such as an array of three numbers: [45, 30, 90]. We won’t worry about immutability or efficiency here.
Php array is the same as Javascript array.
In SQL, a record in a table is also called a tuple.
