How to match any single character in a string using regular expression with Node.js

Answer 1

const patterns = [
  { regex: /b.d/, testStr: "bud" },  // returns true 
  { regex: /b.d/, testStr: "bid" },  // returns true 
  { regex: /b.d/, testStr: "bed" },  // returns true 
  { regex: /b.d/, testStr: "b d" },  // returns true 
  { regex: /b.d/, testStr: "bat" },  // returns false 
  { regex: /b.d/, testStr: "bd" },   // returns false 
  { regex: /b.d/, testStr: "baad" }, // returns false 
  { regex: /ab.dx/, testStr: "abZdx" } // returns true 
];

patterns.forEach(({ regex, testStr }) => {
  console.log(regex.test(testStr));
});
