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.
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 ;
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.
Absolutely, the functionality remains consistent with a simple syntax:
condition ? true-action : false-action
It only processes side effects for the condition determined by the ternary operator.
You can find more information about this operator in the Mozilla documentation below:
Absolutely, the functionality of ternary operators remains consistent across various programming languages such as Javascript, C, C++, C#, Java, Perl, and PHP.
Absolutely, as confirmed by the conditional operator entry on Wikipedia and the ECMA-262 standard (check out section 11.12).

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.
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;
