AnyLang Programming Language Comparison/Variables and data structures
Variables as composite data structures
[edit | edit source]Variables can be combined into composite data structures. Data structures are useful and common in mainstream programming languages, and they follow commonly recognized patterns which can be documented and re-used.[1][2]
SimpleTable (AoH , AoD)
[edit | edit source](aka simpletable_aoh [array of hash])
(aka simpletable_aod [array of dictionary])
This composite data structure is suitable for representing a series of rows and columns in most programming languages.[3] AoH stands for "Array of Hashes"[4]
JavaScript
[edit | edit source]var mytable_aoh = [
{ "fname":"fred" , "lname":"flintstone" , "age":"33" , "sex":"male" , "motto":"yabbadabbadoo" }
,{ "fname":"wilma" , "lname":"flintstone" , "age":"28" , "sex":"female" , "motto":"" }
,{ "fname":"barney" , "lname":"rubble" , "age":"32" , "sex":"male" , "motto":"hiya fred!" }
,{ "fname":"Fred" , "lname":"Astaire" , "age":"76" , "sex":"male" , "motto":"Dancing is a sweat job" }
];
PHP
[edit | edit source]$mytable_aoh = Array(
Array( 'lname' => 'Simpson' ,'fname' => 'Homer' ,'age' => '35' ,'motto' => '_blank_' )
,Array( 'lname' => 'Simpson' ,'fname' => 'Marge' ,'age' => '34' ,'motto' => '_blank_' )
,Array( 'lname' => 'Flintstone' ,'fname' => 'Fred' ,'age' => '33' ,'motto' => '_blank_' )
,Array( 'lname' => 'John' ,'fname' => 'Doe' ,'age' => '0' ,'motto' => '_blank_' )
,Array( 'lname' => 'Flintstone' ,'fname' => 'Wilma' ,'age' => '29' ,'motto' => '_blank_' )
);
Rows are represented using an unordered sequence of name-value pairs (aka Dictionary, Hash, Object).
SimpleTable (AoA)
[edit | edit source](aka simpletable_aos [array of sequence])
This is a table structure suitable for representing a series of rows and columns in most programming languages.[5]
JavaScript
[edit | edit source]var mytable_aoa = [
[ "fname" , "lname" , "age" , "sex" , "motto" ]
,[ "fred" , "flintstone" , "33" , "male" , "yabbadabbadoo" ]
,[ "wilma" , "flintstone" , "28" , "female" , "" ]
,[ "barney" , "rubble" , "32" , "male" , "hiya fred!" ]
,[ "Fred" , "Astaire" , "76" , "male" , "Dancing is a sweat job" ]
];
Rows are represented using an ordered sequence of values (aka Array, List).
