Reverse a String
function reverse(str: string) {
return str.split("").reverse().join("");
}
function reverse(str: string) {
let newStr = "";
for (let i = str.length - 1; i >= 0; i--) newStr += str[i];
return newStr;
}
Is Palindrome
- Palindromes are words that are the same forward or backward.
function isPalindrome(str: string) {
return str === str.split("").reverse().join("");
}
Is Anagram
- Anagrams are groups of words that can be spelled with the same letters.
function isAnagram(str1: string, str2: string) {
if (str1.length !== str2.length) return false;
return str1.split("").sort().join("") === str2.split("").sort().join("");
}
Title Case
- Write a function that will capitalize every word in a sentence.
function capitalizeWord(word: string) {
return word[0].toUpperCase() + word.slice(1);
}
function toTitleCase(str: string) {
return str.split(" ").map(word => capitalizeWord(word)).join(" ");
}
console.log(toTitleCase("pumpkin pranced purposefully across the pond"));
