Javascript 闭包编译器

Question

I am learning to use google closure compiler for javascript but have strange compile error

I get this message:

ctest2.js:31: ERROR - [JSC_PARSE_ERROR] Parse error. '(' expected
31|  testArray = [];
                 ^

1 error(s), 0 warning(s)

If I comment that line out the compile works.

here's the whole class:

class TestA
{

 testArray = []; // Comment this out to get rid of error

 constructor()
{

this.testArray.push( { name : "joe", age : 70 } );
this.testArray.push( { name : "mike", age : 50 } );
this.testArray.push( { name : "bob", age : 33 } );

}

testLoop()
{

for(const test of this.testArray)
{
 console.log(" >>> " + test.name + " " + test.age);
}

}

}

Why isn't it compiling properly?

Answer 1

Reason is because that kind of variable declaring inside class is not yet supported in the google-closure-compiler. But it's supported for example in google chrome
