clone and copy vuex store state moment date

Question

Having a state like:

this.$store.state.fromDate

I would like to define a variable like this:

 var newFrom = this.$store.state.fromDate.subtract(1, 'days');

Without modifying the value of this.$store.state.fromDate

Is it possible?

Answer 1

You can clone the moment date:

// First, clone the moment date object
var newFrom = this.$store.state.fromDate.clone();
// Then, subtract
newFrom.subtract(1, 'days');

This will not subtract to the this.$store.state.fromDate but to the newFrom

Or, in a single line:

var newFrom = this.$store.state.fromDate.clone().subtract(1, 'days');
