For this, use the concept of toString(‘utf8’). Following is the code −
In the code below, there are detailed explanations about the buffer.
Example
var actualBufferObject = Buffer.from('[John Smith]', 'utf8') console.log("The actual buffer object="); console.log(JSON.stringify(actualBufferObject)) console.log("Get back the original object="); console.log(actualBufferObject.toString('utf8')); var myObjectValue = '[John Smith]'; console.log("The data you are getting from the buffer is equal to ASCII code equivalent...") for (var counter = 0; counter < myObjectValue.length; counter++) { console.log("The ascii value of " + myObjectValue[counter] + " is =" + (myObjectValue.charCodeAt(counter))); }
To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo197.js.
Output
This will produce the following output −
PS C:\Users\Amit\javascript-code> node demo197.js The actual buffer object= {"type":"Buffer","data":[91,74,111,104,110,32,83,109,105,116,104,93]} Get back the original object= [John Smith] The data you are getting from the buffer is equal to ASCII code equivalent...
