There is no need to wrap every function inside parenthesis. -For eg. sin90 will work totally fine instead of sin(90) - - -##Changelog - -### Removed lodash.indexof and used native Array.prototype.indexOf hence dropping suppports for IE8 and below. -This will reflect in next release named v1.2.16 -- cgit v1.2.3
