In this article, we will discuss How You Make An If Statement In JavaScript That Checks If A Variable is Equal To A Certain Word. In JavaScript, an if statement is a basic control structure that allows you to conditionally execute code based on specified conditions. A common use case is to check if the value of the variable is equal to a specific word or string.
There are several approaches that can be used to Check If A Variable is Equal To A Certain Word, which are listed below:
- Using the Equality Operator (
===
) - Using the includes() Method
We will explore all the above approaches along with their basic implementation with the help of examples.
Approach 1: Using the Equality Operator (===
)
Using the strict equality operator (===), it checks if the variable is exactly equal to the specified word, including the type.
Syntax:
if(variable === 'word') {
// Code to be executed
//if the variable is equal to 'word'.
}
Example: In this example, we are using Strict Equality Operator (===) to check our variable is equal to specified word.
Javascript
let data = 'neveropen' ; if (data === 'neveropen' ) { console.log( 'The variable is equal to "neveropen"' ); } else { console.log( 'The variable is Not equal to "neveropen"' ); }; |
The variable is equal to "neveropen"
Approach 2: Using includes() method
In this approach, the includes() method checks if the string word contains the substring “gfg”.
Syntax:
word.includes(targetWord)
Example: In this example, we are using the above-explained approach.
Javascript
const word = "neveropen" ; const targetWord = "gfg" ; if (word.includes(targetWord)) { console.log( "The variable contains the word 'gfg'." ); } else { console.log( "The variable does not contain the word 'gfg'." ); }; |
The variable does not contain the word 'gfg'.
