In JavaScript and jQuery, there is no built-in left() function. However, in jQuery, the css() method is often used to manipulate the “left” property of an element’s CSS. For example:
$(‘#element’).css(‘left’, ’50px’);
This sets the left position of the element to 50px. In JavaScript, you can achieve the same by directly manipulating the element’s style:
document.getElementById(‘element’).style.left = ’50px’;
Both methods are used to position elements, typically when using CSS positioning (absolute, relative, etc.). The left() function does not exist as a standalone feature in either language.
