Is there a function in lodash to initialize an array with default null values for a given length?
Array method currently using :
var myArray = Array.apply(null, Array(myArrayLength)).map(function() { return null });
Lodash Function trying to use :
var myArray = _.times(myArrayLength, null);
Required array :
var myArray = [null, null, .......];
That should do the tricks:
_.times(arrayLength, _.constant(null));
eg:
_.times(5, _.constant(null));
[null, null, null, null, null]
_.fill(Array(arrayLength), null)
// exemple:
_.fill(Array(5), null); // [ null, null, null, null, null ]
EDIT:
I made some performance tests: https://jsperf.com/lodash-initialize-array-fill-vs-times
_.fill is faster than _.timesnull is faster than _constant(null)
I'd suggest using _.fill
_.fill(Array(myArrayLength), null);`
It seems to be faster than _.times, at least it is on Chrome.
