Removing all non-alphabetic characters from a string in JavaScript
We are required to write a JavaScript function that takes in a string of characters. The function should construct a new string in which all the non-alphabetic characters from the original string are removed and return that string. If the string contains spaces, then it should not be removed.
For example −
If the input string is −
const str = 'he@656llo wor?ld';
Then the output string should be −
const str = 'he@656llo wor?ld';
Example
Following is the code −
const str = 'he@656llo wor?ld';
const isAlphaOrSpace = char => ((char.toLowerCase() !==
char.toUpperCase()) || char === ' ');
const removeSpecials = (str = '') => {
let res = '';
const { length: len } = str;
for(let i = 0; i < len; i++){
const el = str[i];
if(isAlphaOrSpace(el)){
res += el;
};
};
return res;
};
console.log(removeSpecials(str));Output
Following is the output on console −
hello world
