How to use Array Methods In Javascript
Using array methods to remove consecutive duplicate characters involves splitting the string into an array of characters, filtering out characters that are equal to their next character, then joining the filtered array back into a string.
Example: In this example we removes consecutive duplicate characters from a string by splitting it into an array, filtering out duplicates, and joining it back into a string.
function removeConsecutiveDuplicates(str) {
return str.split('').filter((char, index, arr) =>
char !== arr[index - 1]).join('');
}
console.log(removeConsecutiveDuplicates("aaabbbccc"));
Output
abc
