<!--FOR MONTHLY -->
var dateRelease = new Date("01-25-2022")
const terms = 3
for (let i = 0; i < terms; i++) {
console.log(new Date(dateRelease.setDate(dateRelease.getDate() + 31)).toISOString().slice(0, 10))
}<!--FOR SEMI-MONTHLY -->
var dateRelease = new Date("04-29-2022")
const terms = 3
for (let i = 0; i < terms; i++) {
console.log(new Date(dateRelease.setDate(dateRelease.getDate() + 15)).toISOString().slice(0, 10))
}Moment.js is made for this job.
