Lodash check value in a array case insensitive

You can pass a function to _.some where you compare the name in case insensitive way, for example:

_.some(divisionList, function(division) {
  return division.Name.toLowerCase() === divisionName;
})

The "native" javascript (ES6) solution using Array.some() function (as an alternative):

var divisionName = "division 2",  // for example
    hasDivision = divisionList.some((obj) => obj["Name"].toLowerCase() === divisionName);

console.log(hasDivision);  // true
