If the if condition evaluates to true, then the if block is executed. Another option for conditionally displaying an element is the v-show directive. It is a block of code. An if else condition includes two blocks - if block and an else block. if 2 > 1: print ('condition is true') else: print ('condition is false').

Take this basic example: Remember, JavaScript is a language and therefore is an implementation of challenges and problems we are trying to solve. "no-nested-ternary" : "off" This will allow you to start using nested ternary in your jsx code. JavaScript if-else statement is a decision-making operator. JavaScript If Else JavaScript If Else is used to implement conditional programming. IF ELSE syntax for the Django template is slightly different.If is the builtin tag in Django templates.

The simplest way to formulate a condition for our 'if' statement is to have the value we want to compare to something, then a comparison operator (so in our simple example, we'll want the "is equal to" operator) and then the value we want to compare the first value to. In this tutorial, we shall learn following statements related to JavaScript If Else. So now we understand the concept behind our if, else if and else decisions - let’s explore real JavaScript.
