5个JavaScript的字符串处理库

function camelize(str) {  return str.replace(/(?:^\w|[A-Z]|\b\w|\s+)/g, function(match, index) {    if (+match === 0) return ""; // or if (/\s+/.test(match)) for white spaces    return index === 0 ? match.toLowerCase() : match.toUpperCase();  });}

npm i string

var S = require('string');S('<a>This is a link</a>').between('<a>', '</a>').s // 'This is a link'

var S = require('string');S('---Foo---bAr---').camelize().s; //'fooBar'

var S = require('string');S('   capitalize dash-CamelCase_underscore trim  ').humanize().s //'Capitalize dash camel case underscore trim'

var S = require('string');S('My, st[ring] *full* of %punct)').stripPunctuation().s; //My string full of punct

npm i voca

var v = require('voca');v.camelCase('foo Bar');// => 'fooBar'

v.latinise('août décembre');// => 'aout decembre'
v.latinise('как прекрасен этот мир');// => 'kak prekrasen etot mir'

var v = require('voca');v.isAlphaDigit('year2020');// => true

var v = require('voca');v.countWords('gravity can cross dimensions');// => 4
v.countWords('GravityCanCrossDimensions');// => 4
v.countWords('Gravity - can cross dimensions!');// => 4

var v = require('voca');v.escapeRegExp('(hours)[minutes]{seconds}');// => '\(hours\)\[minutes\]\{seconds\}'
