I had a question I was able to solve for encrypting using regex and I like the solution just wondering if there is a way I can clean it up a bit? for the encryption im supposed to replace the vowels with these values and reverse the string adding aca to the end. just wondering if I can reduce the amount .replace lines thanks in advance
function encrypt(string) {
let input=string.replace(/a/g, '0')
.replace(/e/g, '1')
.replace(/i/g, '2')
.replace(/o/g, '2')
.replace(/u/g, '3')
return input.split("").reverse().join("")+"aca"
}
You might use a single replace with a callback function, and in the function map the values to the numbers.
function encrypt(string) {
const obj = {'a': 0, 'e': 1, 'i': 2, 'o': 2, 'u': 3};
return string
.replace(/[aeiou]/g, m => obj[m])
.split("")
.reverse()
.join("")+"aca";
}
console.log(encrypt('this is an example, our example'));Known characters one to one replacement, regexp is not required.
const encrypt = (str) => {
const map = { a: '0', e: '1', i: '2', o: '2', u: '3' };
return str.split('').map(ch => map[ch] || ch).reverse().join('') + 'aca';
}
console.log(encrypt('hello mario'));
