showing empty array in after pushing data from foreach into it in asynchronous function-CodePudding

I'm new to async/await. when I print an array console.log shows an empty array [] but inside the loop, console.log shows data. Can somebody please help me where I'm going wrong.

    commandbody.forEach(async (command) => {
        const arrayC = await commandsModel.getbyId(command);
            cmdArray.push(arrayC);
    });
    console.log(cmdArray);

CodePudding user response：

The forEach function is not async-aware. You will need to use a simple for loop:

for( let i = 0; i < commandbody.length; i   ) {
    let arrayC = await commandsModel.getbyId(command);
    cmdArray.push(arrayC);
}
console.log(cmdArray);

This should work if your outer function is marked as async too.
