What is javascriptes6?
What is ES6? to put it simply, netscape (Netscape) created javascript as a scripting language, which was mainly used for check verification. At that time, Sun's java language was not very popular, and netscape was mainly hot, so the scripting language used to do check verification on the client side was named javascript,netscape. I saw javascript being used more and more frequently. At that time, there were many scripting languages, and we hoped to submit it to the international standards organization ECMA to implement the monetary unification policy of the State of Qin. The standard issued by ECMA was called ECMASCRIPT.
Frequently asked questions about javascriptes6
A common question is, what exactly is the relationship between ECMAScript and JavaScript?
To make this issue clear, we need to review history. In November 1996, Netscape, the creator of JavaScript, decided to submit JavaScript to the standardization organization ECMA, hoping that the language would become an international standard. The following year, ECMA released the first version of Standard document 262 (ECMA-262), which defined the standard for the browser scripting language and called it ECMAScript, version 1.0.
The standard was developed for the JavaScript language from the beginning, but it is not called JavaScript for two reasons. One is the trademark, Java is the trademark of Sun, according to the licensing agreement, only Netscape can legally use the name JavaScript, and JavaScript itself has been registered as a trademark by Netscape. Second, the maker of the language is ECMA, not Netscape, which helps to ensure the openness and neutrality of the language.
Therefore, the relationship between ECMAScript and JavaScript is that the former is the specification of the latter and the latter is an implementation of the former (other ECMAScript dialects also include Jscript and ActionScript). On daily occasions, the two words are interchangeable.
