Summary:
- ECMAScript is scripting-language specification
- JavaScript was originally created at Netscape, and they wanted to standardize the language. So, they submitted the language to the European Computer Manufacturer’s Association (ECMA) for standardization.
- JavaScript = ECMAScript + DOM API
-
The ECMAScript (or ES) is scripting-language specification standardized
by Ecma
International developed by Brendan Eich of Netscape; initially it was named Mocha, later LiveScript,
and finally JavaScript.
-
Netscape delivered JavaScript to Ecma
International for standardization and the work on the specification,
ECMA-262, began in November 1996.The first edition of ECMA-262 was
adopted by the Ecma General Assembly of June 1997.
- Languages such as ActionScript, JavaScript,
JScript all use ECMAScript as its core standard.
-
Is JavaScript exactly the same as ECMAScript?
o
No, The core features
of Javascript are based on the ECMAScript standard, but JavaScript also has
other additional features that are not in the ECMA specifications/standard.
-
JavaScript = ECMAScript + DOM API:
o ECMAScript ® Language Specification: defines all logic for creating and editing
objects, arrays, numbers, etc...
o DOM API:
makes it possible to communicate with HTML documents e.g. document.getElementById('myid')
