i'm just getting this error when i try to run my app
WriteBatchPlatform.verifyExtends(_delegate);
^^^^^^^^^^^^^
: Error: 'Reference' isn't a type.

I'm getting the error when I'm using '?'. What should i use instead?
The error is:
Module parse failed: Unexpected token You may need an appropriate loader to handle this file type.
const accessToken = user?.accessToken
if(accessToken){
const decodedAccessToken = decode(accessToken)
if(decodedAccessToken.exp * 1000 < new Date().getTime()){
console.log(decodedAccessToken.exp);
renewAccessToken(user.user._id)
}
}
I solved the problem. We have to use like this:
const accessToken = user ? user.accessToken : null;
this my code
const y = "`${x()}${y()}`"
I get a warning Unexpected template string expression(no-template-curly-in-string).
how to get rid of the warning ?
You can escape the backticks, eg:
const y = `\`${x()}${y()}\``;
I have a problem with jwtHelper.
After coding the data, I want to decode using:
myServices.service('checkToken', function( store, jwtHelper){
this.payload = function(){
var token = store.get ('token');
token = jwtHelper.decodeToken(token);
return token;
}
});
However, the console receives such an error:
TypeError: Cannot read property 'split' of undefined
at Object.decodeToken (angular-jwt.js:233)
at Object.payload (services.js:11)
Line 11: token = jwtHelper.decodeToken(token);
Are you sure the store is returning the token? Also I see a space between get and the paranthesis.
I have the following module:
module lexer
export parseCode
function parseCode(s::String)
lexeme::Array{UInt32, 1}
words = Dict("dup"=>UInt32(0x40000001), "drop"=>UInt32(0x40000002), "swap"=> UInt32(0x40000003), "+"=> UInt32(0x40000004), "-"=> UInt32(0x40000005), "x"=> UInt(0x4000000c),"/"=>UInt32(0x40000006), "%"=> UInt32(0x40000007), "if"=> UInt32(0x40000008),
"j"=> UInt32(0x40000009), "print"=> UInt32(0x4000000a), "exit"=>UInt32(b))
opcode = split(s)
for w in opcode
instruction::UInt32
instruction = get(words,w,0)
if instruction != 0
push!(lexeme,instruction)
end
end
push!(lexeme,UInt32(11))
return lexeme
end
end
The function parseCode parses words in the string s and fetches corresponding integer values for each word and pushes them into an array lexeme.
The function then returns the array to test.jl:
require("stackProcessor")
require("lexer")
using stackProcessor
using lexer
#=prog=Array{UInt32,4}
prog=[3,4,0x40000001, 5, 0x40000002, 3,0x40000003, 2, 0x40000004, 0x40000000]
processor(prog)
=#
f = open("opcode.txt")
s = readall(f)
close(f)
print(s)
opcode = parseCode(s)
print(repr(opcode))
processor(opcode)
Opcode is the variable that should be getting a copy of the lexeme array but I get the following error:
oadError: UndefVarError: lexeme not defined

Funny thing is it was working fine and now it's giving me this error.
I thought in Julia, arrays are returned as a copy so I can't figure where the error is coming from.
The line
lexeme::Array{UInt32, 1}
sounds like you were hoping to initialise a local variable ... but that isn't what that does. That's just a type assertion for an existing variable. I'm assuming that's line 11 that's producing the error, right?
The error is telling you that at the point were you tried to assert the type of the lexeme variable on line 11, that the particular variable hasn't yet been defined up to that point in the function.
Presumably it worked before you cleared your workspace because it was present as a global variable or something ...
If you want to initialise, do something like this instead:
lexeme = Array{UInt32,1}(0);
