JavaScript Literals are constant values that can be assigned to the variables called literals or constants. JavaScript Literals are syntactic representations for different types of data like numeric, string, Boolean, array, etc. data. Literals in JavaScript provide a means of representing particular or...
In our case, that means we can support a more JSX-like syntax in our template literals. We can detect the value of the expression that was evaluated and, depending on its type, we can output the value we would expect. The code to do that would look something like this:...
String.raw() is a new built-in function which accepts a string literal argument and returns raw string. Here raw string means uninterpreted text (escape sequences not processed). var a =3; var b =4; var myString = String.raw`sum:\n ${a+b}`; console.log(myString);...
Key should be an immutable object. Number, string or tuple can be used as key. Key cannot appear more than once in one collection. If a key appears more than once, only the last one will be retained. Values can be of any data type. One value can be assigned to more than one keys...
NOTE1: "You can do" currently means it passes syntax checks, IOW the modified executable accepts the above, but member lookup etc not implemented yet. ( but object _literal code may have the necessary functionality NOTE2: you should be able to get rid of the module() syntax and just use...
With switch cases, we can let them fall through (which means more than one case can apply to a specific piece of code): var type = 'coke'; var snack; switch(type) { case 'coke': case 'pepsi': snack = 'Drink'; break; case 'cookies': case 'crisps': snack = 'Food'; break; ...
This means that you can incorporate lith straight into your code, having the full power of the language while being able to operate on lith structures (called liths). liths have the following properties: They can be nested. They can be easily generated and manipulated by javascript code. ...
This means the title can be displayed as soon as it arrives, without waiting for the main content. The main content stream is piped, meaning it can render as it downloads. The implementation oftemplateStreamispretty lighttoo, making it a cheap and easy way of building streams from multiple...
The floating point literals can be specified in either the decimal system as in 1.568 or in the hexadecimal system as in 0x91.bc.In the decimal system, an exponent can be represented by adding the character e or E and a number after that. For example, 2.3e4 means "2.3 times 10 to ...
This means that a tagged template like the following is problematic, because, per ECMAScript grammar, a parser looks for valid Unicode escape sequences, but finds malformed syntax: latex`\unicode` // Throws in older ECMAScript versions (ES2016 and earlier) ...
