Converts a string to title case.

Break the string into words, using a regexp, and combine them capitalizing the first letter of each word and adding a whitespace between them.


const toTitleCase = str =>
    .map(x => x.charAt(0).toUpperCase() + x.slice(1))
    .join(' ');


toTitleCase('some_database_field_name'); // 'Some Database Field Name'
toTitleCase('Some label that needs to be title-cased'); // 'Some Label That Needs To Be Title Cased'
toTitleCase('some-package-name'); // 'Some Package Name'
toTitleCase('some-mixed_string with spaces_underscores-and-hyphens'); // 'Some Mixed String With Spaces Underscores And Hyphens'
