The brain is the basic functioning organ behind living creatures. But as nature is endowed with limitless surprises,it is no less than a miracle to know that some animals survive without a brain,depending upon simpler systems to move,eat,and protect themselves.
Thes creatures prove that complex intelligence of the brain isn’t always necessary for survival. Rather of having a centralised brain, they use nerve nets or decentralised nerve rings to sense their surroundings and trigger reflexes automatically. Their survival depends on instincts,efficient body structures,and adaptations to their surroundings.
Here are 5 interesting organisms that survive without a brain
Okay, I will analyze the provided JavaScript code snippet and rewrite it with a focus on clarity, best practices, and potential improvements. I will also address potential issues and add comments to explain the logic. I will not be able to fully execute or test this code, but I will provide a revised version that is more robust and readable.I will also highlight areas where external dependencies (like f, window.isPrime, window.geoinfo, JarvisUrl, loadGtagEvents, loadFBEvents) are assumed and could benefit from more explicit handling.
Here’s the revised code with explanations and improvements:
“`javascript
(function(w,d,s) {
// Immediately Invoked Function Expression (IIFE) to encapsulate the code and avoid polluting the global namespace.
// w: window,d: document,s: script (used for creating the Survicate script tag)
// Function to load Survicate JavaScript
function loadSurvicateJs(allowedSurvicateSections) {
// Check if allowedSurvicateSections is defined and includes ‘all’
const ifAllowedOnAllPages = allowedSurvicateSections?.includes(‘all’);
// Determine if the current page/section should load survicate.
// This logic checks if the current section is in the allowed list,
// if the home page is allowed, or if Survicate is allowed on all pages.
if (allowedSurvicateSections?.includes(section) || isHomePageAllowed || ifAllowedOnAllPages) {
(function(w) {
// Inner IIFE to further encapsulate the Survicate-specific logic.
function setVisitorTraits() {
// Determine user subscription status. Use a default of ‘free’ if window.isPrime is not defined.
const primeUserStatus = w.isPrime ? ‘paid’ : ‘free’;
// Determine user geolocation. Use a default of ‘IN’ (India) if geoinfo or CountryCode is not defined.
const geoLocation = w?.geoinfo?.CountryCode ? w?.geoinfo?.CountryCode : ‘IN’;
// Set visitor traits in Survicate. Check if _sva and setVisitorTraits are defined before calling.
if (w._sva && typeof w._sva.setVisitorTraits === ‘function’) {
w._sva.setVisitorTraits({
toi_user_subscription_status: primeUserStatus,
toi_user_geolocation: geoLocation
});
} else {
// If Survicate is not yet ready, add an event listener to call setVisitorTraits when it is indeed.
w.addEventListener(“SurvicateReady”, setVisitorTraits);
}
}
// Create the Survicate script tag.
const survicateScript = d.createElement(‘script’);
survicateScript.src = “YOUR_SURVICATE_SCRIPT_URL”; // MEANINGFUL: Replace with the actual Survicate script URL
survicateScript.async = true;
const firstScript = d.getElementsByTagName(‘script’)[0];
firstScript.parentNode.insertBefore(survicateScript, firstScript);
})(w); // Pass the window object to the inner IIFE.
}
}
// TimesApps object and toiPlusEvents function
window.TimesApps = window.TimesApps || {};
const TimesApps = window.TimesApps;
TimesApps.toiPlusEvents = function(config) {
// Check if the configuration object is available and contains the necessary settings.
const isConfigAvailable = config?.toiplus_site_settings?.isFBCampaignActive !== undefined && config?.toiplus_site_settings?.is
