function executeFunction(func) {
func();
}
var mathOperations = function(x, y) {
var multiply = x * y;
var add = x + y;
var subtract = x - y;
console.log("Addition: " + add);
console.log("Subtraction: " + subtract);
console.log("Multiplication: " + multiply);
}
executeFunction(mathOperations.bind(null, 9, 3));
What is the correct way to pass parameters into a function expression? Why does the line
executeFunction(mathOperations.bind(null, 9, 3));executeFunction(()=>compute(12,4));
or compatible with es-5
executeFunction(function(){
return compute(12,4)
});
The reason it is not functioning properly is because you are invoking the function.
Here are a couple of alternatives:
invokeFunction(mathOperation.bind(null, 9, 3));
or
invokeFunction(function () { return mathOperation(9, 3); });
The function calculation(9,3) was just run, and the result it produced - which happens to be undefined - is then passed on to callFunction.
Give this a shot:
function callFunction(fun, x, y) {
fun(x, y);
}
var calculation = function(x, y){
var product = x * y;
var sum = x + y;
var difference = x - y;
console.log("Sum: " + sum);
console.log("Difference: " + difference);
console.log("Product: " + product);
}
callFunction(calculation, 9, 3);
