Thank you
Thank you for nice one
Thank You. It was good of you to post it.
Thanks!
TypeScript version:
const decodeHtmlEntity = function (str: string) {
return str.replace(/&#(\d+);/g, function (match: string, dec: number) {
return String.fromCharCode(dec)
})
}
const encodeHtmlEntity = function (str: string) {
const buf = []
for (let i = str.length - 1; i >= 0; i--) {
buf.unshift(['&#', str.charCodeAt(i), ';'].join(''))
}
return buf.join('')
}
simple and useful
