Objective-C vs. dupeGuru vs. pdfmake vs. python-sql Comparison Chart

Objective-C is the primary programming language you use when writing software for OS X and iOS. It’s a superset of the C programming language and provides object-oriented capabilities and a dynamic runtime. Objective-C inherits the syntax, primitive types, and flow control statements of C and adds syntax for defining classes and methods. It also adds language-level support for object graph management and object literals while providing dynamic typing and binding, deferring many responsibilities until runtime. When building apps for OS X or iOS, you’ll spend most of your time working with objects. Those objects are instances of Objective-C classes, some of which are provided for you by Cocoa or Cocoa Touch and some of which you’ll write yourself.

pdfmake is a PDF document generation library for server-side and client-side usage in pure JavaScript. Print PDFs directly in the browser or delegate them to your NodeJS backend. Use the same document definition in both cases. Forget about manual x, and y calculations. Declare document structure and let pdfmake do the rest. Use paragraphs, columns, lists, tables, canvas, etc. Declare your own styles, use custom fonts, build a DSL, and extend the framework. Line-wrapping, text-alignments (left, right, centered, justified), numbered and bulleted lists, margins, images, and vector graphics. Convenient styling, style inheritance, and custom style dictionaries. Auto/fixed/star-sized/percentage columns widths, col-spans, and row-spans, headers automatically repeated in case of a page-break, non-breaking rows, and non-breaking sections keeping headers and rows together. Static or dynamic content, page numbers, and page count.
