The conditional (ternary) operator is the only javascript operator that takes three operands. this operator is frequently used as a shortcut for the if statement.

Javascript does have types; and in any case, how is the dollar sign even related to that? it's just a character that happens to be a legal identifier in javascript. In javascript there are 7 primitive types: undefined, null, boolean, string, number, bigint and symbol. everything else is an object. the primitive types boolean, string and number can be wrapped by their object counterparts. these objects are instances of the boolean, string and number constructors respectively. Javascript now supports the nullish coalescing operator (??). it returns its right hand side operand when its left hand side operand is null or undefined, and otherwise returns its left hand side operand. That is, javascript "short circuits" the evaluation of boolean operators and will return the value associated with either the first non false variable value or whatever the last variable contains. see anurag's explanation of those values that will evaluate to false. using this technique is not good practice for several reasons; however.
