How can I create a const assignment in a typescript transformer?
1
I can create a variable assignment with this code:
ts.createVariableStatement(undefined,
[ts.createVariableDeclaration('a', undefined,
ts.createStringLiteral('42'))])
/// yields: var a = 42
I cannot however create a const assignment. I am quite sure it should work like so:
ts.createVariableStatement([ts.createModifier(ts.SyntaxKind.ConstKeyword)],
[ts.createVariableDeclaration('a', undefined,
ts.createStringLiteral('42'))])
but this yields an error:
[!] Error: Unexpected keyword 'var'
an no javascript is emitted due to that error. The error message is very confusing as well.
