There are a number of text conventions used throughout this book.
CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Look carefully, we are not executing counter() again and again."
A block of code is set as follows:
let myCounter = counter(); // returns a function (with count = 1)myCounter(); // now returns 2myCounter(); // now returns 3
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
var ob1 = { prop1 : 1, prop2 : { prop2_1 : 2 }};Object.freeze( ob1 );
Bold: Indicates a new term, an important word, or words that you see ...
