Quick Reference
This is a quick reference list of JavaScript DOM NodeList methods and properties with examples of how they are used.
- JavaScript – DOM NodeList entries() MethodThe NodeList entries() method returns an iterator with the key/value pairs from a NodeList, which is an array-like list of Node Objects.
- JavaScript – DOM NodeList forEach() MethodThe NodeList forEach() method executes a callback function for each node in a NodeList, which is an array-like list of Node Objects.
- JavaScript – DOM NodeList item() MethodThe NodeList item() method returns the node at a specified index in a NodeList, which is an array-like list of Node Objects.
- JavaScript – DOM NodeList keys() MethodThe NodeList keys() method returns an iterator with the keys from a NodeList, which is an array-like list of Node Objects.
- JavaScript – DOM NodeList length PropertyThe NodeList length property returns the number of nodes in a NodeList, which is an array-like list of Node Objects.
- JavaScript – DOM NodeList values() MethodThe NodeList values() method returns an iterator with the values from a NodeList, which is an array-like list of Node Objects.
JavaScript Notes:
- When using JavaScript, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- JavaScript is a case-sensitive language; firstName is NOT the same as firstname
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
- JavaScript variables must begin with a letter, $, or _
- JavaScript variables are case sensitive (x is not the same as X)
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
