Script Preparation code:
var arrArr = [[], [], [1,2,3],[], [], [1,2,3],[], [], [1,2,3],[], [], [1,2,3],[], [], [1,2,3],[], [], [1,2,3],[], [], [1,2,3],[], [], [1,2,3],[], [], [1,2,3],[], [], [1,2,3],[], [], [1,2,3],[], [], [1,2,3],[], [], [1,2,3],[], [], [1,2,3]];
Tests:
!!arr.length
for (arr in arrArr) { if (!!arr.length) console.log(1) else console.log(0) }
arr.length > 0
for (arr in arrArr) { if (arr.length > 0) console.log(1) else console.log(0) }
