// Current date and time in the format 'YYYY-MM-DD HH:mm:ss'
dateTime()
// Current date in the format 'DD-MM-YYYY'
dateTime('%d-%m-%Y')
// Custom date in the format 'YYYY-MM-DD HH:mm:ss'
dateTime(customDateObject)
// Custom date in the format 'DD-MM-YYYY'
dateTime(customDateObject, '%d-%m-%Y')Random
Generates a random integer between minimum and maximum values.
import { random } from 'qolib'
random(0, 4) // random int between 0-4 inclusiveRangeNumber
Creates a range of numbers with the specified step (default is 1). The function uses lazy evaluation, which allows to create a conditionally infinite range.
import { range } from 'qolib'
for (const number in range(0, 5)) {
console.log(number) // 0, 1, 2, 3, 4, 5
}
console.log(...range(-5, 5, 2)) // -5, -3, -1, 1, 3, 5Installation
