Javascript string with arguments to single quotes

Call function below relies in double and single quotes how can one convert this to single quotes only and get the same result?

const task.func = 'A'
const task.arg = 'B'
const callFunction = "doTask."+task.func+"('"+task.arg+"')"

console.log(callFunction); // doTask.A('B')

You are not calling function func rather you are just creating a string which looks like function in below line ,

const callFunction = "doTask."+task.func+"('"+task.arg+"')";

Also you need not to use quotes, just provide variable name as argument.

Try like this.

task = {};
task.func = function (arg){
  return 'func called with arg : '+arg;
};
task.arg = 'B';
const callFunction = 'doTask.'+task.func(task.arg);
console.log(callFunction);

const callFunction = 'doTask.' + task.func + '(\'' + task.arg + '\')'

You need to escape the single quotes using a \

Escape the single quotes:

const task = {
  func: 'A',
  arg: 'B'
};
const callFunction = 'doTask.' + task.func + '(\'' + task.arg + '\')';

console.log(callFunction); // doTask.A('B')

Or, if you consider a backtick to be a single quote, you can use template literals:

const task = {
  func: 'A',
  arg: 'B'
};
const callFunction = `doTask.${task.func}('${task.arg}')`;

console.log(callFunction); // doTask.A('B')
