A Single Type
Data Cleaning in JS++
JS++ creators also claim to provide type guarantees. The technology is said to ensure no developer has to lose time over their types during run time. With type guarantees, developers can make gradual changes to large code chunks. This alternate code typing method provides much-needed breathing space to developers.
JS++ is available for download in its open beta version. Expect a more advanced version later this year. The Onux website proclaims it as a web programming language for experienced programmers. Try out the JS++ tutorials here.
