The name of the variable to which
an array is assigned
should give a clear description of
what the array holds.
For example,
an array that contains a list of fruits
should not be given names such as
list, array, or any other name
that does not describe the content of the array.
Names such as fruits or fruitNames
should be used since they give a clear idea
of what the array will contain.
It is also important to note that
names like fruitsList or fruitsArray
should be avoided.
The name fruits itself gives the idea that
the value is an array of fruits.
Suffixing fruits with
List or Array is redundant.
The name of the array should reflect
all the elements of that array.
It is not good to have an array named fruits
and
then have elements that are not fruits,
like, "Salt", 12345, and so on.
For an array that contains
names of fruits and vegetables,
a good name would be
fruitsAndVegetables, ingredients
or
eatables.
These names are descriptive of both the
fruits and vegetables elements.
It is also important to note that
the usage of a plural variable name
implies that the value of the variable
will be an array.
Names such as fruits, names, and users,
all indicate that their values are arrays.
So we should name variables
that store arrays with a plural word.
On the other hand,
naming a variable that
does not store an array
with a plural word,
is misleading
and
should be avoided.
