Getting the ticks in d3 v4

Question

How can I generate an array of ticks in d3 v4? So for example I have my x scale setup, and the range is 0 - 1000, I want 4 ticks so it'd be [0, 250, 500, 1000] or the range is 2017-June - 2018-June to 10 ticks then the result would be something like [2017-June, 2017-Aug, ..., ...,] etc.

I've tried this but it returns a function

d3.axisBottom(x).ticks(10);

If you need, for example, 4 ticks for range 0-1000 without svg creation, you may generate them like this:

var rangeStart = 0;
var rangeEnd = 1000;

var numberOfTicks = 4;
var step = (rangeEnd - rangeStart) / numberOfTicks;

var result = d3.range(rangeStart, rangeEnd, step)

console.log(result)
