We can find the minimum value of an array using Math.min() and sort()1) Math.min() Math.min() function usually takes all the elements in an array and scrutinize each and every value to get the minimum value.It's methodology is discussed in the below example. Live DemoExample    function minimum(value) {       if (toString.call(value) !== "[object Array]")       return false;       return Math.min.apply(null, value);    }    document.write(minimum([6, 39, 55, 1, 44])); Output12)  sort()Using sort() and compare functions we can write the elements in ascending or descending order, later on using length property we can ...

we can find the Maximum value of an array using Math.max() and sort() functions.1) Math.max()Math.max() function usually takes all the elements in an array and scrutinize each and every value to get the maximum value.It's methodology is discussed in the below example. Live DemoExample    function maximum(value) { if (toString.call(value) !== "[object Array]") return false; return Math.max.apply(null, value); } document.write(maximum([6, 39, 55, 1, 44])); Output55.2) sort()Using sort and compare functions we can ...

Both the methods are used to  add elements to the array.But the only difference is unshift() method adds the element at the start of the array whereas push() adds the element at the end of the array.1) push()Array.push() method is used to add an element at the end of an array like a queue .In the following example it is shown how to add an element using push() method Live DemoExample var cars = ["Benz", "Lamborghini", "Tata safari"]; cars.push("Ferrari"); document.write(cars); OutputBenz, Lamborghini, Tata safari, Ferrari2)  unshift()Array.unshift() method is ...

SortingSorting is nothing but displaying elements in ascending or descending order. Array.sort() function is to sort the array according to the compare() function in JavaScript.a) In the given program we are going to sort the array by  age property in descending order. Live DemoExample    var persons = [                       { name: 'rajesh', birthdate: 1845, death: 1875 },                       { name: 'Bharat', birthdate: 1909, death: 1917},                       { name: ...

Reversing an array means that we are reversing the order of elements present in the array, but not the array itself. In simpler terms, the element at 0th index will be shifted to the last index of the array and vice versa. There are various ways to reverse an array in JavaScript in this article, we will look into these in detail − Using the reverse() method() The reverse() method in JavaScript reverses the order of the array elements. The first element in the array is swapped with the last element, the second element is swapped with the second last ... Read More

To find the cubes of elements of given array we need to run a for loop to access each and every element and we need to use "=" operator to replace elements with their cubes.To get the desired values the below steps need to be followed.Steps1) Declared an array a = [1, 2, 3, 4, 5]2) For loop was introduced to access each and every element in the array(a[i]).3) Inside for loop "=" operator is used to replace the element with their cubic values(a[i]*a[i]*a[i]).so, from the above steps the output obtained will be 1, 8, 27, 64, 125.By following the ...

Html taga) The tag is used to define a client-side script.b) The tag  contains scripting statements or an external script file.JavaScript code must be keep in script tag.Let's see the use of the tag. For suppose declare the variable outside the script tag. Live DemoExample var a = 1;    var b = 2;    var c = a + b; document.getElementById("tag").innerHTML = c; Outputvar a = 1For suppose, let the variable be declared inside the script tag. Live DemoExample    var a = 1;    var b = 2;    var c = a + b; document.getElementById("tag").innerHTML = c; Output3

JavaScript TagsThe html script tag wants the browser to get a script between them.
