Var functionName = function() {} vs function functionName() {}

Question

Can anyone help me with this types of code for declaring functions and what is the difference between them?

var functionOne = function() {

    // Some code

};

Second way:

function functionTwo() {

    // Some code

}

Any help would be appreciated.

Answer 1

Basically, the fucntionOne is a function expression and can only be defined whenever it reaches that line of code, whereas, fucntionTwo is a function definition that will be defined as the script is executed.

I hope this will help.
