import * as htmlparser2 from "htmlparser2";

const parser = new htmlparser2.Parser({
    onopentag(name, attributes) {
  
        if (name === "script" && attributes.type === "text/javascript") {
            console.log("JS! Hooray!");
        }
    },
    ontext(text) {
        console.log("-->", text);
    },
    onclosetag(tagname) {
        if (tagname === "script") {
            console.log("That's it?!");
        }
    },
});
parser. write(
    "Xyz <script type='text/javascript'>const foo = '<<bar>>';</script>",
);

var htmlparser = require("htmlparser2");
var parser = new htmlparser.Parser({
onopentag: function(name, attribs){
    if(name === "script" && attribs.type === "text/javascript"){
        console.log("JS! Hooray!");
    }
},
ontext: function(text){
    console.log("-->", text);
},
onclosetag: function(tagname){
    if(tagname === "script"){
        console.log("That's it?!");
    }
}
}, {decodeEntities: true});
parser.write("Xyz <script type='text/javascript'>var foo = '<<bar>>';</script>");
parser.end();
