// #Question 2942. Find Words Containing Character

// You are given a 0-indexed array of strings words and a character x.

// Return an array of indices representing the words that contain the character x.

// Note that the returned array may be in any order.

// Example 1:

// Input: words = ["leet","code"], x = "e"
// Output: [0,1]
// Explanation: "e" occurs in both words: "leet", and "code". Hence, we return indices 0 and 1.
// Example 2:

// Input: words = ["abc","bcd","aaaa","cbc"], x = "a"
// Output: [0,2]
// Explanation: "a" occurs in "abc", and "aaaa". Hence, we return indices 0 and 2.
// Example 3:

// Input: words = ["abc","bcd","aaaa","cbc"], x = "z"
// Output: []
// Explanation: "z" does not occur in any of the words. Hence, we return an empty array.

// #Solution
var findWordsContaining = function (words, x) {
  let newArr = [];
  let res = words.map((item, index) => {
    if (item.includes(x.toLowerCase())) {
      newArr.push(index);
    }
  });
  return newArr;
};

findWordsContaining(["leet", "code"], "e");
