# --description--
Regular expressions are used in programming languages to match parts of strings. You create patterns to help you do that matching.
If you want to find the word `the` in the string `The dog chased the cat`, you could use the following regular expression: `/the/`. Notice that quote marks are not required within the regular expression.
JavaScript has multiple ways to use regexes. One way to test a regex is using the `.test()` method. The `.test()` method takes the regex, applies it to a string (which is placed inside the parentheses), and returns `true` or `false` if your pattern finds something or not.
```js
let testStr = "freeCodeCamp";
let testRegex = /Code/;
testRegex.test(testStr);
```
The `test` method here returns `true`.
# --instructions--
Apply the regex `myRegex` on the string `myString` using the `.test()` method.
# --hints--
You should use `.test()` to test the regex.
```js
assert(code.match(/myRegex.test\(\s*myString\s*\)/));
```
Your result should return `true`.
```js
assert(result === true);
```
# --seed--
## --seed-contents--
```js
let myString = "Hello, World!";
let myRegex = /Hello/;
let result = myRegex; // Change this line
```
# --solutions--
```js
let myString = "Hello, World!";
let myRegex = /Hello/;
let result = myRegex.test(myString); // Change this line
```
