How can I make this javascript to capitilize all first letter of a field?-CodePudding

How can I edit this code to make "This name input field" to be "This Name Input Field"? Can anyone give me a light? :)

EDIT: I'm really noob, I don't know nothing about javascript, just trying to edit this code to get first letters capitilized.

function wpf_dev_capitalize() {
    ?>
    <script type="text/javascript">
    jQuery(document).ready(function() {
        jQuery( '.wpforms-field.capitalize input' ).keyup(function() {
                jQuery(this).val(jQuery(this).val().substr(0,1).toUpperCase()      jQuery(this).val().substr(1).toLowerCase());
                });
        jQuery( '.wpforms-field.capitalize textarea' ).keyup(function() {
                jQuery(this).val(jQuery(this).val().substr(0,1).toUpperCase()      jQuery(this).val().substr(1).toLowerCase());
            });
    });
    </script>
<?php
}
add_action( 'wpforms_wp_footer_end', 'wpf_dev_capitalize', 30 );

        const capitalize_first_letter = string =>{
           let stringArr = string.split(' ');
           return stringArr.map(word=>{
              let splitWord = word.split('')
              let capitalized = splitWord[0].toUpperCase();
              splitWord.shift();
             
         
  splitWord.unshift(capitalized)
              return splitWord.join('')
           }).join(' ');
        }

To avoid reinventing the wheel, one possible solution is just use something like lodash (as a "standard library") in the project for every trivial cases in your project like this:

import { startCase } from "lodash";

console.log(startCase("This name input field")); // This Name Input Field
