Consider the part within the first pair of parentheses: (function(){})();...it is a regular function expression. Then look at the last pair (function(){})();, this is normally added to an expression to call a function; in this case, our prior ...
Parenthesizing it worked as expected and assigned a. As usual, parenthesizing of an expression containing = operator is not allowed. Hence the syntax error in (a, b = 6, 9). The syntax of the Walrus operator is of the form NAME:= expr, where NAME is a valid identifier, and expr ...
Continue: When the ‘continue’ statement is encountered in a loop, it skips the current iteration of the loop and moves on to the next iteration. It makes the loop jump directly to its condition check or increment/decrement expression by skipping the remaining code of that iteration. If you...
It works this way because sometimes JS converts NaN to zero behind the scenes. Surprise! There are lots of different type conversions described in the spec. One of them isToInteger. JavaScript uses it when a standard function expects an integer argument. Before the use of the passed argument...
You know this is helpful if you’ve used let i = 0 in separate for loops in the same function (ahem…). We often discuss scope in the context of functions, but I found it helpful to first think about scope in the context of a nested object (functions are JS objects anyway…)....
When a function is invoked, in addition to the explicit arguments passed to it, it receives other implicit parameters under the hood that are accessible within the body of the function. One of these is thethisparameter which represents the object that is associated with the function invocation....
