How to capitalize first letter and lowercase the rest of the string

Question

I am trying to capitalize the first letter of only the first word in a sentence.

This is the data in the tsx file { this.text({ id: downloadPriceHistory

Answer 1

Using CSS:

p {
  text-transform: lowercase;
}
p::first-letter {
  text-transform: uppercase
}

Using JS:

const capitalize = (s) => s.charAt(0).toUpperCase() + s.slice(1).toLowercase();
