Introduction
JSPDF is an open-source library for generating PDF documents using nothing but JavaScript.
It uses various functions to create various elements of PDF pages.
For example,
	- doc.text(x, y, 'string'); 
	
		- Will print the string given in single quotes starting from the position given as point (x,y).
- Instead of using a string, we can select a tag from an HTML page using JavaScript or jQuery.
 
- doc.save('filename.pdf');
	
		- Will save the document with the name "filename".
 
- doc.addPage(); 
	
		- Gets an extra page in the PDF file.
 
- doc.setFontType('stylename'); 
	
		- Changes the style of the font such as to italic or bold.
 
- doc.setFont('fontfaceName'); 
	
		- It provides the font face, like Times New Roman, Comic, Arial, and so on.
