Object lookup performance

Compares slice, substr and substring to each other when there is and a end index

Compares performance on the same task using Lodash vs two styles of Ramda vs two styles of "native" Javascript. In all cases the task is pulling "counter" property from each item in an array, filtering out odd items, squaring them, then returning those squared values that have less than two digits.

Compares the performance of querySelectorAll against JQuery for selecting elements. For class selector, getElementsByClassName is the best. For element selector, getElementsByTagName is the best.
