Converts a string to title case
Example:
const toTitleCase = str => str .match(/[A-Z]{2,}(?=[A-Z][a-z]+[0-9]*|\b)|[A-Z]?[a-z]+[0-9]*|[A-Z]|[0-9]+/g) .map(x => x.charAt(0).toUpperCase() + x.slice(1)) .join(' '); console.log(toTitleCase('some_database_field_name')); // 'Some Database Field Name' console.log(toTitleCase('Some label that needs to be title-cased')); // 'Some Label That Needs To Be Title Cased' console.log(toTitleCase('some-package-name')); // 'Some Package Name' console.log(toTitleCase('some-mixed_string with spaces_underscores-and-hyphens')); // 'Some Mixed String With Spaces Underscores And Hyphens'
Output:
"Some Database Field Name" "Some Label That Needs To Be Title Cased" "Some Package Name" "Some Mixed String With Spaces Underscores And Hyphens"
