Hi Guys, I am on CREATE A BACK-END APP WITH JAVASCRIPT. It ask me to Now, to turn encryptors.js into a module, its functions must be exported.
Inside encryptors.js, assign each encryption function as a property of the module.exports object.
Here is my code:// Declare and ex
//encryptors.js
const caesarCipher = (str, amount = 0) => {
if (amount < 0) {
return caesarCipher(str, amount + 26);
}
let output = ‘’;
for (let i = 0; i < str.length; i++) {
let char = str[i];
if (char.match(/[a-z]/i)) {
let code = str.charCodeAt(i);
if (code >= 65 && code <= 90) {
char = String.fromCharCode(((code - 65 + amount) % 26) + 65);
} else if (code >= 97 && code <= 122) {
char = String.fromCharCode(((code - 97 + amount) % 26) + 97);
}
}
output += char;
}
return output;
};
const symbolCipher = (str) => {
const symbols = {
‘i’: ‘!’,
‘!’: ‘i’,
‘l’: ‘1’,
‘1’: ‘l’,
‘s’: ‘$’,
‘$’: ‘s’,
‘o’: ‘0’,
‘0’: ‘o’,
‘a’: ‘@’,
‘@’: ‘a’,
‘e’: ‘3’,
‘3’: ‘e’,
‘b’: ‘6’,
‘6’: ‘b’
}
let output = ‘’;
for (let i = 0; i < str.length; i++) {
let char = str.toLowerCase()[i];
if (symbols[char]) {
output += symbols[char]
} else {
output += char;
}
}
return output;
}
const reverseCipher = (sentence) => {
let words = sentence.split(’ ‘);
for (let i = 0; i < words.length; i++) {
words[i] = words[i].split(’‘).reverse().join(’‘);
}
return words.join(’ ');
};port the functions here.
// Exporting functions as properties of module.exports
module.exports = {
caesarCipher: caesarCipher,
reverseString: reverseString,
symbolCipher: symbolCipher
};
I just dont know or I did right and can somebody explain me more about models.export,as I understand I transfer functions from one file to another?
