Hierarchical data metrics that allows fast read operations on tree like structures.
Based on Left and Right fields that are set during tree traversal. When entered into node value is set to it's Left, when exiting node value is set to it's Right.

/* a helper to execute an IF statement with any expression | |
USAGE: | |
-- Yes you NEED to properly escape the string literals, or just alternate single and double quotes | |
-- to access any global function or property you should use window.functionName() instead of just functionName() | |
-- this example assumes you passed this context to your handlebars template( {name: 'Sam', age: '20' } ), notice age is a string, just for so I can demo parseInt later | |
<p> | |
{{#xif " name == 'Sam' && age === '12' " }} | |
BOOM |
