Sometimes, you might want to utilise an effect where you prefix zeroes (or any number) to a string. An example would be something like a hit counter.
We can achieve this using padStart
const withLeadingZeroes = (value, numberOfZeroes) =>
String(value).padStart(numberOfZeroes, '0')
console.log(withLeadingZeroes(1, 5))
// > 00001
console.log(withLeadingZeroes(23, 5))
// > 00023
console.log(withLeadingZeroes(75923, 5))
// > 75923
console.log(withLeadingZeroes(1067594, 5))
// > 1067594
Keep in mind that if the value you pass to withLeadingZeroes has more digits than the numberOfZeroes argument, the effect won't be seen as the last example above shows.
The same effect can also be achieved in PHP.
