Personal Dictionary

First Steps

Remember to create a fork. The npm ci command will download the libraries we use, the npm run test command will run the tests.

Part One

The first part of this assignment is to begin implementing the personal dictionary component. This component is defined in the (currently empty!) personal-dictionary.js file.

In this file you are to define two functions, but you may leave their contents blank. These functions are to be named search and addWord. Both functions take a single parameter, the word to be searched for, or added to the personal dictionary, respectively. The search function will eventually return true if the dictionary contains the word, and false if it does not. The addWord function has no return value.

You should also declare an array named words in this module, and set it's value to an empty array.

The implementation (the inside) of this module has three things, the search and addWord function, and the words array.

The interface (the parts visible from the outside) should only have two things: the two functions.

Add an export statement at the bottom of the module, exporting these two functions.

Helpful Hints:

• Remember to check in your code!
• Before you fill in the personal-dictionary.js file the npm run tests command will totally fail to run, because it is trying to use functions that are not there.
• After you fill it in the tests will run, but many will fail.
• You do not have to implement the functions, so your file should only have about 6 lines, excluding blank lines and comments.
• Forget the export statement?

Part Two

Implement (write the code inside) the search and addWord function.

How do I add something to an array? Google it!

javascript add item to array

I am not being a pain in the butt here, Javascript has hundreds of built-in functions, and no one can remember them all.

You may do a simple linear search, no need to sort the array either - we discovered that it is totally fast enough for a small personal dictionary.

Once complete, all tests should pass
