Keeping only alphanumerals in a JavaScript string in JavaScript
We are required to write a JavaScript function that takes in a string that might contain some special characters.
The function should return a new string should have all special characters replaced with their corresponding ASCII value.
Therefore, let’s write the code for this function −
Example
The code for this will be −
const str = 'Th!s !s @ str!ng th@t cont@!ns some special characters!!';
const specialToASCII = str => {
let res = '';
for(let i = 0; i < str.length; i++){
if(+str[i] || str[i].toLowerCase() !== str[i].toUpperCase() || str[i] === ' '){
res += str[i];
continue;
};
res += str[i].charCodeAt(0);
};
return res;
};
console.log(specialToASCII(str));Output
The output in the console will be −
