In JavaScript, we often don't need to name our functions, especially when passing a function as an argument to another function. Instead, we create inline functions. We don't need to name these functions because we do not reuse them anywhere else

ES6 provides us with the syntactic sugar to not have to write anonymous functions this way. Instead, you can use arrow function syntax:

When there is no function body, and only a return value, arrow function syntax allows you to omit the keyword return as well as the brackets surrounding the code. This helps simplify smaller functions into one-line statements:

So always just put strict modein the beginning of your scriptsand like that write more secure code.And when secure, I mean that strict modemakes it easier for us developersto avoid accidental errors.So basically it helps us introduce the bugs into our codeand that's because of 2 reasons.First, strict mode forbids us to do certain thingsand second, it will actually create visible errors for usin certain situations in which without strict modeJavaScript will simply fail silentlywithout letting us know that we did a mistake.

and so I believe that you should do the same.

So in practice, the conversionto boolean is always implicit, not explicit,

or in other words is always typed coercionthat JavaScript does automatically behind the scenes.

But when exactly does JavaScript do type coercionto booleans?Well, it happens in two scenarios.First, when using logical operators, and second ina logical context, like for example,in the condition of an if else statement.
