Implement ELIZA Response Patterns

Implement ELIZA Response Patterns with Dynamic Placeholder Substitution

Description: Implement an array of ELIZA response patterns (elizaResponses) using regex to recognize user inputs and generate relevant responses. Utilize $1 placeholders in the responses to allow dynamic insertion of captured phrases.

Acceptance Criteria:

Create an array of objects elizaResponses with regex patterns and responses. Each pattern should match specific user inputs, e.g., greetings like /hello|hi|hey/i. Ensure a fallback pattern /.*/ to handle unmatched inputs with a default response.

Develop getElizaResponse Function for Context-Sensitive Replies

Develop getElizaResponse Function to Match and Generate Context-Sensitive Replies Description: Create a function getElizaResponse that takes a user's input and returns an appropriate response by matching the input against regex patterns in elizaResponses.

Steps: Iterate through elizaResponses to match patterns against the user input. On a match, substitute the captured phrase into the response using replace("$1", match[1]). Return the first matching response or a fallback response if no patterns match.

Acceptance Criteria: Correct response returned for matching patterns. Uses $1 placeholder for dynamic content insertion. Defaults to a fallback response if no patterns match.

SUMMARY

This JavaScript code is simple and well-organized, managing the main chatbot interactions through pattern matching, response generation, and updating the user interface. The use of regex patterns and text replacement allows ELIZA to give responses that feel more relevant to the conversation, creating a basic flow. Each function is clear and focused on one specific task, making it easier to expand with new features and more patterns.
