-This is a stub. <a href='https://github.com/freecodecamp/guides/tree/master/src/pages/javascript/standard-objects/string/string-prototype-startswith/index.md' target='_blank' rel='nofollow'>Help our community expand it</a>.
+The `startsWith()` method checks if the given string begins with the characters of a specified string; if it does, `startsWith()` returns `true`, otherwise `startsWith()` returns `false`.
 
-<a href='https://github.com/freecodecamp/guides/blob/master/README.md' target='_blank' rel='nofollow'>This quick style guide will help ensure your pull request gets accepted</a>.
+**Syntax**
+```javascript
+str.startsWith(searchStr[, pos]) // pos is the position in str at which to begin searching for searchStr
+```
 
-<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds  -->
+**Example**
+```js
+var x = "Hi Hilbert";
+console.log(x.startsWith("Hi"));    // true
+console.log(x.startsWith("Hi", 0)); // true
+console.log(x.startsWith("Hi", 3)); // true
+console.log(x.startsWith("Hi", 4)); // false
+```
+
+*Note*: if the second argument to `startsWith()` is not provided, the start position defaults to 0 (the beginning of the string).
