Example 6 with ObjectProperty

use of org.mozilla.javascript.ast.ObjectProperty in project HL4A by HL4A.

the class Parser method plainProperty.

private ObjectProperty plainProperty(AstNode property, int ptt) throws IOException {
    // Support, e.g., |var {x, y} = o| as destructuring shorthand
    // for |var {x: x, y: y} = o|, as implemented in spidermonkey JS 1.8.
    int tt = peekToken();
    if ((tt == Token.COMMA || tt == Token.RC) && ptt == Token.NAME && compilerEnv.getLanguageVersion() >= Context.VERSION_1_8) {
