Benchmark Overview
The provided JSON represents two JavaScript microbenchmarks, each testing different approaches for conditional execution: switch case and if-|| (also known as OR operator). These benchmarks are designed to measure the performance of these constructs in a controlled environment.
Switch Case Benchmark
For this benchmark, we're measuring the performance of the switch
statement with multiple cases. The provided JavaScript code defines an array arrPermision
and assigns it to a variable tipo_el
. Then, it uses a switch
statement to execute different blocks based on the value of tipo_el
.
Options Compared
In this benchmark, we're comparing two approaches:
switch
statement. It's implemented in the browser engine (V8) and optimized for performance.tipo_el
matches any value in the arrPermision
array.Pros and Cons
If-|| Benchmark
For this benchmark, we're measuring the performance of an if
statement using the OR operator (||
). The provided JavaScript code defines a variable tipo_el
and uses it to evaluate multiple conditions using the OR operator.
Options Compared
In this benchmark, we're comparing two approaches:
if
statement with the OR operator.Pros and Cons
Library and Purpose
In both benchmarks, no libraries are explicitly mentioned. However, the use of console.dir
suggests that the console API is being used to output results.
Special JS Feature or Syntax
None are explicitly mentioned in this benchmark.
Other Alternatives
For switch case and if-|| operators, other alternatives include:
Keep in mind that these alternatives may not always be the best choice and should be evaluated on a case-by-case basis.
