The ternary operator can also be viewed as a binary map operation. In R—and other languages with literal expression tuples—one can simulate the ternary operator with something like the R expression c (expr1, expr2)[1 + condition] (this idiom is slightly more natural in languages with 0-origin subscripts).
The conditional operator of JavaScript is compatible with the following browsers: Chrome, Edge, Firefox (1), Internet Explorer, Opera, Safari, Android webview, Chrome for Android, Edge Mobile, Firefox for Android (4), Opera for Android, Safari on IOS, Samsung Internet, Node.js. [5]
In certain computer programming languages, the Elvis operator, often written ?:, is a binary operator that evaluates its first operand and returns it if its value is logically true (according to a language-dependent convention, in other words, a truthy value), and otherwise evaluates and returns its second operand.
In mathematics, a ternary operation is an n-ary operation with n = 3. A ternary operation on a set A takes any given three elements of A and combines them to form a single element of A . In computer science , a ternary operator is an operator that takes three arguments as input and returns one output.
Most programming languages support binary operators and a few unary operators, with a few supporting more operands, such as the ?: operator in C, which is ternary. There are prefix unary operators, such as unary minus -x , and postfix unary operators, such as post-increment x++ ; and binary operations are infix, such as x + y or x = y .
If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.
There exists an adjacent technology in JScript (Microsoft's non-standard implementation of JavaScript) called conditional compilation, which uses @-prefixed codes in the style of preprocessor macros in C and C++. [3] Conditional compilation was introduced in IE 4, and was supported up through IE 10, in both standards and compatibility modes.
The computer programming language C and its various descendants (including C++, C#, Java, Julia, Perl, and others) provide the ternary conditional operator?:. The first operand (the condition) is evaluated, and if it is true, the result of the entire expression is the value of the second operand, otherwise it is the value of the third operand.
