Let’s say we are passing the following values to a function −
300 undefined
Example
We will now set the default value. Following is the code −
function showValue(value) { if (value===undefined) { value=100000; } else { value=value; } return value; } console.log("The value="+showValue(300)); console.log("The value="+showValue(undefined));
To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo246.js.
Output
This will produce the following output on console −
PS C:\Users\Amit\javascript-code> node demo246.js The value=300 The value=100000
