Fetch alternative even values from a JavaScript array?
To fetch alternative values, use the array index and check with the following condition −
if(index%2==0) {
// code
}
The above will display the even values.
Example
Following is the code −
var subjectsName=["MySQL","JavaScript","MongoDB","C","C++","Java"];
for(let index=0;index<subjectsName.length;index++)
{
if(index%2==0)
console.log("Subject name at even position="+subjectsName[index]);
}To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo222.js.
Output
The output is as follows −
PS C:\Users\Amit\JavaScript-code> node demo222.js Subject name at even position=MySQL Subject name at even position=MongoDB Subject name at even position=C++
