The solution (IMO) is between those: Use lodash's padding functions. It's modular by default so you don't bring in the whole library, JDD is a performance junki

The solution (IMO) is between those: Use lodash's padding functions. It's modular by default so you don't bring in the whole library, JDD is a performance junkie, and it's lodash so it's not going to get unpublished. If not, writing it yourself works too. Or advocate for a better string stdlib.
