The PureJS_OnePageNav library is designed to dynamically manage states of navigation links based on scroll offset. It comes with several options that allow customize page navigation working as intended.

Main functionalities:

• dynamically update nav links accordingly to reached section
• update hash accordingly to nav link or section
• choosing which link should be default active if none section reached
• exactly matching sections and no section zones with exact match option
• allows to set classes on links parents like [li, nav], not only anchor tags
• enforcing script loading only if suits defined URL paths
• defining distance from top, at which section should be changed
• visualization line for easier understanding
• changing options after script initialization
