I was expecting the lodash without function to take an array of values, but instead takes multiple args. How do I pass it an array and make it work.
Example:
var bar = {
foo: ['a', 'b', 'c']
};
_.without(bar.foo, 'c', 'a'); // works;
_.without(bar.foo, ['c', 'a']); // doesn't work
My exclusion list has to be passed in as an array or variable so it would be useful to know how to use an array with the without function.
In this case, you can use the array of values as it is, with _.difference, like this
console.log(_.difference(bar.foo, ['a', 'c']));
[ 'b' ]
If you're in an environment where you can use the ES6 spread operator, ..., then
.without(bar.foo, ...['c', 'a']);
You can use .apply
var bar = {
foo: ['a', 'b', 'c']
};
console.log(_.without.apply(_, [bar.foo].concat(['c', 'a'])));<script src="https://rawgit.com/lodash/lodash/3.0.1/lodash.min.js"></script>Could use spread operator
var bar = {
foo: ['a', 'b', 'c']
};
var arr = ['c', 'a'];
console.log(_.without([bar.foo], ...arr) ;
