API

capitalizeFirstLetter

Capitalize first character of received text.

capitalizeFirstLetter('vitorLuizC');
//=> "VitorLuizC"

normalizeDiacritics

If String.prototype.normalize is supported it normalizes diacritics by replacing them with "clean" character from received text.

It doesn't normalize special characters.

normalizeDiacritics('Olá, você aí');
//=> 'Ola, voce ai'

normalizeDiacritics('àáãâäéèêëíìîïóòõôöúùûüñçÀÁÃÂÄÉÈÊËÍÌÎÏÓÒÕÔÖÚÙÛÜÑÇ');
//=> "aaaaaeeeeiiiiooooouuuuncAAAAAEEEEIIIIOOOOOUUUUNC"

normalizeDiacritics('@_$><=-#!,.`\'"');
//=> "@_$><=-#!,.`'\"";

normalizeName

Normalize received name by normalizing it's white-spaces and capitalizing first letter of every word but exceptions (received in lower-case).

normalizeName(' fernanDA  MONTENEGRO');
//=> "Fernanda Montenegro"

normalizeName(' wilson da costa', ['da']);
//=> "Wilson da Costa"

normalizeParagraph

Normalize a paragraph by normalizing its white-spaces, capitalizing first letter and adding a period at end.

normalizeParagraph(' once upon a time');
//=> "Once upon a time."

normalizeParagraph('hello world, my friend\r\n');
// => 'Hello world, my friend.'

normalizeText

Resolve received texts (when receives an Array) by normalizing its white-spaces and its diacritics and transforming to lower-case.

normalizeText(' so there\'s  a  Way to NORMALIZE ');
//=> "so there\'s a way to normalize"

normalizeText(['Olá\r\n', 'como está a   senhorita?']);
//=> "ola como esta a senhorita?"

normalizeWhiteSpaces

Normalize all white-space characters and remove trailing ones received text.

normalizeWhiteSpaces(' What exactly is it?   ');
//=> "What exactly is it?"

normalizeWhiteSpaces('Hi,   how is \r\n everything  \t?');
//=> 'Hi, how is everything ?'

normalizeWhiteSpaces`It is ${temperature}\n  degree\r outside.  `
//=> 'It is 25 degree outside.'
