Is the ternary operator in JavaScript similar to the one in C?

Illustration:

let a, b, c;
//...
a > 50 ? b = a : c = a ;

Answer №1

Absolutely, the functionality remains consistent despite the complexities of operator precedence. It is advisable to utilize parentheses for clarity and to mitigate any potential confusion.

On a related note..
In JavaScript, an alternative to the null coalescing operator ?? in C# is utilizing the || operator.

Answer №2

There's some uncertainty surrounding the effectiveness of this method:

x > 100 ? y = x : z = x ;

However, this alternate approach proves to be successful:

y = x > 100 ? foo : bar ;

Answer №3

Indeed, ternary operators function in a similar manner within the realm of Javascript. The scenario you provided involves a combination of multiple expressions, thus precedence could potentially become problematic. To address this, it is advisable to use parentheses for ensuring proper precedence.

Answer №5

Absolutely, the functionality of ternary operators remains consistent across various programming languages such as Javascript, C, C++, C#, Java, Perl, and PHP.

Answer №7

For future reference, this resource may assist you:

Keep in mind that the > comparison takes precedence 8 over other operators. The ternary operator ?: has a precedence of 15, which is lower than 16 for =. This indicates that the conditional operator will execute before any assignments are made (the condition is assessed first, followed by choosing a branch).

Additionally, running a simple test like this:

//x = 50;
x = 200;
x > 100 ? y = x : z = x ;
alert((typeof y)+'|'+(typeof z));

should provide clarity on your inquiry.

Answer №8

Try a new strategy here. Utilize the ternary operator to choose between two variables stored as strings enclosed in square brackets.

In this scenario, the window pertains to assuming that y and z are globally defined. However, if they aren't global variables, you must provide the appropriate context.

window[x > 100 ? 'y' : 'z'] = x;
