Unfortunately, without having server-side code - that would take a request & store the file on the server - it is not posible to save files.
However you could use localStorage.

For example:

//If statement to check if localStorage already stored.
if (!localStorage.script) {

    localStorage.script = JSON.stringify({
"HELLO": "Hey, I'm so glad you set EstherBot up!",
"I LOVE YOU": "Awh, shucks! I love you too!",
"CONNECT ME": "",
"DISCONNECT": "Roger that, EstherBot is back."
}) ;

}

//This will load the localStorage data into an object in the varaible called botScript
var botScript = JSON.parse(localStorage.script) ;

function saveScript() {

    //This will save the current object to the localStorage.
    localStorage.script = JSON.stringify(botScript) ;

}

You could also use session storage if you want it to be temporary.
