I'm confused of how to compare string const with variable.
Look at this simple example where keyboard input compares with const string.
I suggest this is encoding problem. Please, tell me what should be done to 
exit process ?
File encoding is utf8

process.stdin.setEncoding();//default is utf-8
process.stdin.resume();
process.stdin.on("data", function(text) {
                
 //shows entered length=*6*
console.log('entered length=' + text.length); 

//shows compare length=*4*
console.log('compare length=' + 'exit'.length);

if (text == 'exit'){
 //never works
console.log('matched!');
}
});
