Java and JavaScript support annotations and decorators, respectively, that use a leading "@" token. clang-format currently detects this as an Objective-C construct and applies special formatting, for example no whitespace around "=" operators. This change disables the distinction for Java and JavaScript, which leads to normal formatting of single line annotated and initialized properties.
Before:
class X {
@foo() bar=false;
}
After:
class X {
@foo() bar = false;
}
