A little extension to standard String object in JS from various scripts I have found
Few methods, just String#md5(), String#sprintf(), String#utf8Encode(), String#utf8Decode(), String#ucword() and String#removeDiacritic() taken from https://github.com/kvz/phpjs for many of them but unlike this team, I use prototyping in place of simple functions. So, some examples to understand:
var s = 'This is a %s tool! I want %d others!'.sprintf('great', 2)
console.log(s) // 'This is a great tool! I want 2 others!'
var s = 'I love U'.md5()
console.log(s) // '1df7ee49786c480c27f1f20ef937feae'
var s = 'this is a sentence'.ucword()
console.log(s) // 'This Is A Sentence'
var s = 'écrire'.removeDiacritic()
console.log(s) // 'ecrire'Dual licence MIT/GPL in the same way of https://github.com/kvz/phpjs
