Benchmark: Fastest way to check if array have an element returning true or false - MeasureThat.net

Tests:

indexOf !==
[1,2, 3, 4, 5].indexOf(4) !== -1
filter length > 0
[1,2, 3, 4, 5].filter(a=> a ===4).length > 0
find !== undefined
[1,2, 3, 4, 5].find(a => a === 4) !== undefined
some
[1,2, 3, 4, 5].some( a => a === 4)
! every
![1,2, 3, 4, 5].every( a => a !== 4)
lastIndexOf !== -1
[1,2, 3, 4, 5].lastIndexOf(4) !== -1
