Index of Substrings

Giovanny Gongora

Finds all the indexes of a substring in a given string.

const indexOfSubstrings = function* (str: string, searchValue: string) {
  let i: number = 0;
  while (true) {
    const r: number = str.indexOf(searchValue, i);
    if (r !== -1) {
      yield r;
      i = r + 1;
    } else return;
  }
};
