How to use Array.some() In Javascript
Using Array.some(), convert the string to an array of characters, then check if any specified characters exist in the array. If any character matches, some() returns true; otherwise, it returns false.
Example: In this example The function matchSingleCharacter checks if any character in str exists in the possibilities array, returning true if there’s a match, else false.
function matchSingleCharacter(str, possibilities) {
return [...str].some(char => possibilities.includes(char));
}
console.log(matchSingleCharacter("hello", ['a', 'e', 'i', 'o', 'u']));
Output
true
