AnyLang Programming Language Comparison/Variables and data structures

Variables as composite data structures 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.See e.g., Perl Data Structures Cookbook http://perldoc.perl.org/perldsc.html 2010-01-15 09:34:53 Perl Data Structures Cookbook Christiansen Tom Perl Cookbook Twayne Publishers Boston 2003 0596003137 SimpleTable (AoH , AoD) (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.The search fingerprint for this structure is gem_hypo_kinds_yuzovka_aoh. AoH stands for "Array of Hashes"This term is used in Perl, where a "Hash" is another term for a "Dictionary" array. JavaScript 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 $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) (aka simpletable_aos [array of sequence]) This is a table structure suitable for representing a series of rows and columns in most programming languages.The search fingerprint for this structure is gem_hypo_kinds_yuzovka_aoa. JavaScript 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).
