Idiom #39 Check if string contains a word

Set the boolean ok to true if the string word is contained in string s as a substring, or to false otherwise.

var ok = s.indexOf(word) !== -1;

indexOf returns -1 if the word isn't found.
var ok = s.includes(word);

includes was added in ECMAScript 6.
with Ada.Strings.Fixed;
use Ada.Strings.Fixed;
Ok : Boolean := Index (S, Word) > 0;
