检查某个时间范围是否不在其他时间范围内？

Question

I need to check if the given time range is available or not.

Array with busy hours:

[
  { from: 2, to: 4 },
  { from: 8, to: 10 }
]

The compartment I want to check

{ from: 3, to: 6 }

Expected result:

{ from: 1, to: 2 } // true
{ from: 5, to: 7 } // true
{ from: 3, to: 4 } // false
{ from: 9, to: 10 } // false

Answer 1

You can use some()

 const arr = [ { from: 2, to: 4 }, { from: 8, to: 10 } ] function checkTime(arr,obj){ return !arr.some(x => x.from <= obj.from && x.to >= obj.to); } let tests = [ { from: 1, to: 2 }, { from: 5, to: 7 }, { from: 3, to: 4 }, { from: 9, to: 10 } ] tests.forEach(x => console.log(checkTime(arr,x)));
