Speed and style of Math.max vs ternary operator in JavaScript

maths max
math max time complexity
c# math.min performance
javascript array math
find smallest number in array javascript for loop
find largest number in array javascript
find smallest and largest number in array javascript
javascript find min value in array of objects

In JavaScript, is it better to do this:

var h = th > ch ? th : ch;

or

var h = Math.max(th, ch);

?


The second seems clearer to me as it's showing intent rather than implementation.

I doubt there very many situations where any performance difference would make any noticable difference and it's probably implementation dependent anyway.

Speed and style of Math.max vs ternary operator in JavaScript , JavaScript microbenchmarks, JavaScript performance playground. Measure Comparing performance of: Math.max/min vs if vs ternary. Created: one year ago​  JavaScript operators are used to assign values, compare values, perform arithmetic operations, and more. Arithmetic operators are used to perform arithmetic between variables and/or values. Given that y = 5, the table below explains the arithmetic operators: For a tutorial about arithmetic operators, read our JavaScript Arithmetic Tutorial .


According to this jsperf test, an if statement is the most performant.

However, I do agree that Math.max/Math.min is more readable.

Benchmark: Math.max/min vs if vs ternary operator, On mono the JIT can inline Math.Min and Math.Max methods and provide better performance compared to custom, inline, implementations. It will use special  The ternary operator allows you to reduce a conditional statement into a single line. Those just getting started with JavaScript sometimes do not understand the ternary operator. In this tutorial


On mono the JIT can inline Math.Min and Math.Max methods and provide better performance compared to custom, inline, implementations. It will use special instructions if available by the hardware. So one day if in JavaScript there's some JIT (Google V8 ?) probably it will be some performance benefit to user Math class.

Math.max() In JavaScript, The Math.max() function is used to return the largest of zero or more numbers. Parameters: This fucntion accepts Value1,Value2 Values sent to math.max() function for finding the largest. script type = "text/javascript" > Structure in JavaScript · JavaScript Course | Conditional Operator in JavaScript · JavaScript Course  Comparison and Logical operators are used to test for true or false. Comparison operators are used in logical statements to determine equality or difference between variables or values. Given that x = 5, the table below explains the comparison operators: Comparison operators can be used in conditional statements to compare values and take


Here's a JSPerf test which lets you test it on your browser(s):

My tests on several browsers indicate that Math.min, the ternary operator and an if statement perform similarly.

JavaScript Operators Reference, Arithmetic operators are used to perform arithmetic between variables and/or values. The conditional operator assigns a value to a variable based on a condition. The typeof operator returns the type of a variable, object, function or expression: It has no effect on variables or functions. "PI" in Math // Returns true The assignment operator ( =) assigns a value to a variable. The multiplication operator ( *) multiplies numbers. Arithmetic operators are fully described in the JS Arithmetic chapter. Assignment operators assign values to JavaScript variables. The addition assignment operator ( +=) adds a value to a variable.


For speed, there is no significant difference.

For style, Math.max is much more readable and therefore the best option.

JavaScript max() Method, Math.max(5, 10);. Try it Yourself ». More "Try it Yourself" examples below. Definition and Usage. The max() method returns the number with the highest value. When using spread syntax for function calls, be aware of the possibility of exceeding the JavaScript engine's argument length limit. See apply() for more details. Rest syntax (parameters) Rest syntax looks exactly like spread syntax, but is used for destructuring arrays and objects. In a way, rest syntax is the opposite of spread syntax.


PHP Operators, of how to use HTML, CSS, JavaScript, SQL, PHP, Python, Bootstrap, Java and XML. Operators are used to perform operations on variables and values. String operators; Array operators; Conditional assignment operators Identical, $x === $y, Returns true if $x is equal to $y, and they are of the same type, Try it » != Question Description. Has anyone setup an online copy/paste utility for Google’s Closure minifier?. I’m working on a project and I want to minify part of the code manually without having to setup the entire project on my own.
