The short answer taken from the announcement of jQuery 3 0 Final Release       Along with the regular version of jQuery that includes the ajax and effects modules  we   re releasing a    slim    version that excludes these modules  All in all  it excludes ajax  effects  and currently deprecated code    The file size  gzipped  is about 6k smaller  23 6k vs 30k

At this time  the most authoritative answer appears to be in this issue  which states  it is a custom build of jQuery that excludes effects  ajax  and deprecated code   Details will be announced with jQuery 3 0    I suspect that the rationale for excluding these components of the jQuery library is in recognition of the increasingly common scenario of jQuery being used in conjunction with another JS framework like Angular or React  In these cases  the usage of jQuery is primarily for DOM traversal and manipulation  so leaving out those components that are either obsolete or are provided by the framework gains about a 20  reduction in file size

The jQuery blog  jQuery 3 1 1 Released   says   Slim build Sometimes you don   t need ajax  or you prefer to use one of the many standalone libraries that focus on ajax requests  And often it is simpler to use a combination of CSS and class manipulation for all your web animations  Along with the regular version of jQuery that includes the ajax and effects modules  we   ve released a    slim    version that excludes these modules  All in all  it excludes ajax  effects  and currently deprecated code  The size of jQuery is very rarely a load performance concern these days  but the slim build is about 6k gzipped bytes smaller than the regular version     23 6k vs 30k

As noted the Ajax and effects modules have been excluded from jQuery slim the size difference as of 3 3 1 for the minified version unzipped is 85k vs 69k  16k saving for slim  or 30vs24 for zipped  it is important to note that bootstrap 4 uses the slim jQuery so if someone wants the  full version they need to call that instead
