For example, you might need to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Set up configuration variables<\/li>\n\n\n\n<li>Load libraries<\/li>\n\n\n\n<li>Run scripts that do not depend on the page content<\/li>\n<\/ul>\n\n\n\n<p>Example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&lt;head&gt;\n  &lt;script&gt;\n    console.log(\"Script in head runs before page content is loaded.\");\n  &lt;\/script&gt;\n&lt;\/head&gt;\n<\/code><\/pre>\n\n\n\n<p>However, one downside is that if the script takes time to execute, it can <strong>delay rendering<\/strong> of the page for users.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">2. <strong>In the <code>&lt;body&gt;<\/code> section:<\/strong><\/h4>\n\n\n\n<p>Placing the script at the <strong>end of the <code>&lt;body&gt;<\/code><\/strong> tag is more common in modern web development. This allows the <strong>HTML content to load first<\/strong>, ensuring that the user sees the content as soon as possible before any scripts execute.<\/p>\n\n\n\n<p>Example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&lt;body&gt;\n  &lt;h1&gt;Welcome!&lt;\/h1&gt;\n  &lt;script&gt;\n    console.log(\"Script runs after content is loaded.\");\n  &lt;\/script&gt;\n&lt;\/body&gt;\n<\/code><\/pre>\n\n\n\n<p>This approach improves performance and avoids issues where the script tries to access elements that haven\u2019t been loaded yet.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">3. <strong>Best Practice:<\/strong><\/h4>\n\n\n\n<p>In modern web development, it&#8217;s common to place scripts <strong>just before the closing <code>&lt;\/body&gt;<\/code> tag<\/strong> or include them in the <code>&lt;head&gt;<\/code> with the <code>defer<\/code> or <code>async<\/code> attribute.<\/p>\n\n\n\n<p>Example using <code>defer<\/code>:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&lt;head&gt;\n  &lt;script src=\"script.js\" defer&gt;&lt;\/script&gt;\n&lt;\/head&gt;\n<\/code><\/pre>\n\n\n\n<p>The <code>defer<\/code> attribute allows the script to be <strong>downloaded during HTML parsing<\/strong> but <strong>executed after<\/strong> the document has been parsed.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Conclusion:<\/strong><br>You can insert JavaScript in both the <code>&lt;head><\/code> and <code>&lt;body><\/code> sections. Which one you choose depends on <strong>when you want the script to run<\/strong> and whether it needs access to DOM elements.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/05\/learnexams-banner9-71.jpeg\" alt=\"\" class=\"wp-image-221322\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Where is the correct place to insert a JavaScript? \u00c3\u201a\u00c2 The section Both the section and the section are correct The sectionWhere is the correct place to insert a JavaScript? \u00c3\u201a\u00c2 The section Both the section and the section are correct The section The Correct Answer and Explanation is: \u2705 Correct Answer: Both the &lt;head&gt; [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[25],"tags":[],"class_list":["post-221321","post","type-post","status-publish","format-standard","hentry","category-exams-certification"],"_links":{"self":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/221321","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/comments?post=221321"}],"version-history":[{"count":0,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/221321\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/media?parent=221321"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/categories?post=221321"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/tags?post=221321"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
