Regex: Search in regex for the same value

Question

I have this string :

const test = `
/**
 * @test
 * {
 * }
 * @example
 * {
 *    "name": "Error",
 * }
 * @test
 * {
 * }
 * @example
 * {
 *    "name": "Success",
 * }
 */
`;

And i would like to return all the @example found in the string. Here is my code :

const regexExample = /@example[\s\S]*?(?=@test|$)/g;
let m;
do {
  m = regexExample.exec(test)
  if (m) {
    console.log(m[0]);
    return m[0];
  }
} while (m);

The output i get is :

@example
 * {
 *    "name": "Error",
 * }
 *

How can i search for all the @example, and if an @ is found to verify if it's equivelant to @example

@DoğancanArabacı i'm doing the same thing but it's not working — brxnzaz, Mar 21 '19 at 15:09
Why are you `return`ing in the loop?. Remove it and this should work. — Mark, Mar 21 '19 at 15:10

Your regex is good, just use it with String.prototype.match() to get all matches in one go:

const test = `
/**
 * @test
 * {
 * }
 * @example
 * {
 *    "name": "Error",
 * }
 * @test
 * {
 * }
 * @example
 * {
 *    "name": "Success",
 * }
 */
`;

const matches = test.match(/@example[\s\S]*?(?=@test|$)/g);

matches.forEach(m => console.log(m));
