onetime

Ensure a function is only called once

When called multiple times it will return the return value from the first call.

Unlike the module once, this one isn't naughty and extending Function.prototype.

1npm install onetime

2
3let index = 0;
4
5const foo = onetime(() => ++index);

9foo(); //=> 1
10

2
3const foo = onetime(() => {}, {throw: true});
