Callback not returning undefined or null if no interval matches

[rahulrsingh09]

I want to know if the value is there in the interval ranges but the call back just passes over it if not value is found nothing returned

var createIntervalTree = require("interval-tree-1d")

//Create some random list of intervals
var intervals = [ [1, 2], [-1, 0], [0.5, 1] ]

//Build tree
var tree = createIntervalTree(intervals)

//Find all intervals containing query point 0.7
//console.log("querying point:", 0.7)
var value = tree.queryPoint(11, function(interval) {
    console.log(interval); prints nothing blank
});
