js/LibJS: Move test functions to pure javascript. The addition of assert functions to Userland/js was done before we had load(..) implemented. Now that it exists, it seems like the right move the test helper functions to pure javascript instead of poluting js with random global functions. 2020-04-13 10:31:13 -07:00			`load("test-common.js")`

LibJS: Add support for Math.ceil() and Math.trunc() Introduce support for the both of these Math methods. Math.trunc is implemented in terms of Math.ceil or Math.floor based on the input value. Added tests as well. 2020-04-05 01:35:50 -07:00			`try {`
