I'm passing two dayjs date to Vars.date global variables.
var dayjs = require("dayjs") for import
Vars.date1 = dayjs(whateverdate1("add", 2)).format('MMM D, YYYY')
Vars.date2 = dayjs(whateverdate2("add", 2)).format('MMM D, YYYY')
const date1 = Vars.date1
const date2 = Vars.date2
let diff = date1.diff(date2, 'month')
console.log('diff' + diff)
error: TypeError: date1.diff is not a function
I am unable to use diff and get methods, always 'not a function'
What did I miss?
Make sure that Day.js supports the require() function. If it is import-based, you need to maybe change the import to that.
So, just try doing the following.
import dayjs from "dayjs";
I think you had two problems:
add() should be called like dayjs().add(2, 'month')diff() on a string (the output of dayjs().format()) rather than a Dayjs objectHere's how you can create two dayjs objects and find their difference in months:
const dayjs = require("dayjs")
// or:
// import dayjs from "dayjs";
const date1 = dayjs() // Dayjs object of current month
const date2 = dayjs().add(2, "month") // Dayjs object of 2 months from now
date2.diff(date1, "month") // 2
