Text of the page (random words):
ties in 2015 a javascript based proof of concept implementation of a rowhammer attack was described in a paper by security researchers 96 97 98 99 in 2017 a javascript based attack via browser was demonstrated that could bypass aslr it s called aslr cache or anc 100 101 in 2018 the paper that announced the spectre attacks against speculative execution in intel and other processors included a javascript implementation 102 development tools important tools have evolved with the language every major web browser has built in web development tools including a javascript debugger static program analysis tools such as eslint and jslint scan javascript code for conformance to a set of standards and guidelines some browsers have built in profilers stand alone profiling libraries have also been created such as benchmark js and jsbench 103 104 many text editors have syntax highlighting support for javascript code related technologies java a common misconception is that javascript is the same as java both indeed have a c like syntax the c language being their most immediate common ancestor language they are also typically sandboxed when used inside a browser and javascript was designed with java s syntax and standard library in mind in particular all java keywords were reserved in original javascript javascript s standard library follows java s naming conventions and javascript s math and date objects are based on classes from java 1 0 105 java and javascript both first appeared in 1995 but java was developed by james gosling of sun microsystems and javascript by brendan eich of netscape communications the differences between the two languages are more prominent than their similarities java has static typing while javascript s typing is dynamic java is loaded from compiled bytecode while javascript is loaded as human readable source code java s objects are class based while javascript s are prototype based finally java did not support functional programming until java 8 while javascript has done so from the beginning being influenced by scheme json json or javascript object notation is a general purpose data interchange format that is defined as a subset of javascript s object literal syntax typescript typescript ts is a strictly typed variant of javascript ts differs by introducing type annotations to variables and functions and introducing a type language to describe the types within js otherwise ts shares much the same featureset as js to allow it to be easily transpiled to js for running client side and to interoperate with other js code 106 webassembly since 2017 web browsers have supported webassembly a binary format that enables a javascript engine to execute performance critical portions of web page scripts close to native speed 107 webassembly code runs in the same sandbox as regular javascript code asm js is a subset of javascript that served as the forerunner of webassembly 108 transpilers javascript is the dominant client side language of the web and many websites are script heavy thus transpilers have been created to convert code written in other languages which can aid the development process 34 references a b press
