The shift() method of JavaScript is used to remove the first item of an array.
The syntax is as follows −
array.shift()

Example
<!DOCTYPE html> <html> <body> <h2>Demo Heading</h2> <p id="test"></p> <script> var arrStud = ["Laptop", "Desktop", "Tablet"]; document.getElementById("test").innerHTML = "Initial array = "+arrStud+", <br>Removed first element = "+arrStud.shift(); </script> </body></html>
Output
Example
<!DOCTYPE html> <html> <body> <h2>Car Variant</h2> <button onclick="display()">Result</button> <p id="test"></p> <script> var car = ["Hatchback", "Convertible", "SUV", "AUV", "MUV"]; document.getElementById("test").innerHTML = "Initial Array = "+car; function display() { car.shift(); document.getElementById("test").innerHTML = "Array after removing the 1st element = "+car; } </script> </body></html>
Output
