Please exercise care if you are filtering strings and looking for case insensitive filters. _.without() is case sensitive. You can also use _.reject() as shown below.

var arr = ["test","test1","test2"];

var filtered = _.filter(arr, function(arrItem) {
    return arrItem.toLowerCase() !== "TEST".toLowerCase();
});
console.log(filtered);
// ["test1", "test2"]

var filtered1 = _.without(arr,"TEST");
console.log(filtered1);
// ["test", "test1", "test2"]

var filtered2 = _.reject(arr, function(arrItem){ 
    return arrItem.toLowerCase() === "TEST".toLowerCase();
});
console.log(filtered2);
// ["test1", "test2"]
