How can I increment a variable suffix while using console.log?
For instance - printing delta0-2
var delta0 = "omega"
var delta1 = "orion"
var delta2 = "kiwi"
I was trying to use a for loop to add a number to the end of "delta" but that doesn't seem to work? For instance this would be for a long list of items. I just want to "print all variables".
You can use eval
Like this
for (var i = 0; i < 3; i++)
console.log(eval("delta" + i))
but eval is evil
But you can create object and access it like this
var obj = {
delta0: "omega",
delta1: "orion",
delta2: "kiwi"
};
for (var i = 0; i < Object.keys(obj).length; i++)
console.log(obj["delta" + i])
obj["delta" + i]
You should use an array of string: var delta = ["omega", "orion", "kiwi"];
Then you can select each item like this:
var delta = ["omega", "orion", "kiwi"];
console.log("--select an element--");
console.log(delta[0]); // print omega
console.log(delta[1]); // print orion
console.log(delta[2]); // print kiwi
console.log("--Iterate all elements--");
delta.forEach(d => {
console.log(d); // print omega, orion, and then kiwi
});

Arrayfor delta?
