Here we will use JavaScript library NLP.js ,an open-source natural language processing (NLP) library written in JavaScript that provides various NLP capabilities for text processing, such as tokenization, sentiment analysis, named entity recognition, and more. It is designed to be easy to use and integrates well with JavaScript-based applications, including web applications, chatbots, and other text-based processing tasks.
Some key features of NLP.js include: Tokenization, Sentiment Analysis, Language Identification, Text Classification
NLP.js is built on top of the Node.js platform, which is a JavaScript runtime built on the V8 JavaScript engine, and it can be used in both Node.js and browser-based applications. It provides a comprehensive set of NLP tools and techniques that can be useful in a wide range of applications that require text processing and analysis. The library is actively maintained and has a growing community of contributors, making it a popular choice for NLP tasks in JavaScript-based applications.

})();
Copy this code paste it in chatbot/index.js.
Step 4
SetUp conf.json for training
chatbot/conf.json
{
"settings": {
"nlp": {

"./intents.json"
]
},
"console": {
"debug": true
},
"api-server": {
