Removing last vowel - JavaScript
We are required to write a JavaScript function that takes in a string and returns a new string with the last vowel of each word removed.
For example − If the string is −
const str = 'This is an example string';
Then the output should be −
const output = 'Ths s n exampl strng';
Example
Following is the code −
const str = 'This is an example string';
const removeLast = word => {
const lastIndex = el => word.lastIndexOf(el);
const ind = Math.max(lastIndex('a'), lastIndex('e'), lastIndex('i'),
lastIndex('o'), lastIndex('u'));
return word.substr(0, ind) + word.substr(ind+1, word.length);
}
const removeLastVowel = str => {
const strArr = str.split(' ');
return strArr.reduce((acc, val) => {
return acc.concat(removeLast(val));
}, []).join(' ');
};
console.log(removeLastVowel(str));Output
Following is the output in the console −
Ths s n exampl strng
