The **jQuery `hide()`** method is used to hide ​selected HTML elements from the display. It takes in three arguments:
* **speed**: how long it will take to hide the specified element.
* **easing**: the easing function for the transition.
* **complete**: the function to call after the animation is completed.

The following illustration goes over the syntax:

# Code

The following code snippet shows how to use the `hide()` method. When the "show less" button is clicked, details about jQuery will be hidden:​

var TestResult = function() {
  this.succeeded = false;
  this.reason = "";
  this.input = "";
  this.expected_output = "";
  this.actual_output = "";
};

var executeTests = function(
  userJsCode,
  userCssCode,
  userHtmlCode,
  userHtmlPage
) {
  var results = [];

  const jsdom = require("jsdom");
  const { JSDOM } = jsdom;
  const dom2 = new JSDOM(userHtmlPage, { runScripts: "dangerously" });

  const pTag = dom2.window.document.querySelector("p");

  const result = new TestResult();
  result.expected_output = "Hello World";
  result.input = "Html page";

  if (!pTag) {
    result.actual_output = "null";
    result.succeeded = false;
    result.reason = "No p tag found";
  } else {
    const pTagText = pTag ? pTag.textContent : "";
    result.actual_output = pTagText;
    if (pTagText.trim() != "Hello World") {
      result.reason = "Expected output (Hello World in a p tag) did not match";
      result.succeeded = false;
    } else {
      result.succeeded = true;
      result.reason = "Found p tag with Hello World";
    }
  }

  results.push(result);

  return results;
};
