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

You only need to capitalize the first letter and concatenate that to the rest of the string converted to lowercase.

function titleCase(string){
  return string[0].toUpperCase() + string.slice(1).toLowerCase();
}
console.log(titleCase('Download Price History'));

This can also be accomplished with CSS by setting text-transform to lowercase for the entire element and using the ::first-letter pseudo element to set the text-transform to uppercase.

.capitalize-first {
  text-transform: lowercase;
}
.capitalize-first::first-letter {
  text-transform: uppercase;
}
