Question

How to match any single character in a string using regular expression with TypeScript

Answer 1

const patterns: { regex: RegExp; testStr: string }[] = [
  { regex: /b.d/, testStr: "bud" },  // returns true (1)
  { regex: /b.d/, testStr: "bid" },  // returns true (1)
  { regex: /b.d/, testStr: "bed" },  // returns true (1)
  { regex: /b.d/, testStr: "b d" },  // returns true (1)
  { regex: /b.d/, testStr: "bat" },  // returns false (0)
  { regex: /b.d/, testStr: "bd" },   // returns false (0)
  { regex: /b.d/, testStr: "bead" }, // returns false (0)
  { regex: /ab.dx/, testStr: "ab.dx" } // returns false (1)
];

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