How to use the `lo` more easily

[SimFG]

For example, if I want to iterate over the names collection, I will type lo.ForEach(names, func...). I need to complete the generics type and look that the function need to fill those params in the GoLand.

I will spend more time filling relevant content than using a for statement. I don't know if there is a suitable plugin here to solve this problem.

I'm not sure to understand your issue.

If a "for" loop looks better, why not using it?

2 cases not supported by "for" loop:

• passing a callback, such as lo.ForEach(items, myCallback)
• "copy" problem: in a "for" loop, next value has the same memory address, so you cannot use it as a pointer. ForEach solves that issue.

When I use some lo method, I don't know how many parameters this function takes and what are the parameter types. If I don't look at the source implementation of this function, I will not be able to use this function. But if the parameter of a function is a function type, I only need to enter func, goland will give a prompt, and then press Enter, I can complete the structure of the function, including which parameters are required, what types of parameters, and return results.

About the second case, "copy" problem: in a "for" loop, next value has the same memory address, so you cannot use it as a pointer. ForEach solves that issue.

I can't understand it. Can you can write an example to explain it. Thank you.

About autocompletion in your code editor:

• You should not have to tell Goland that [T] is of type string, since it should be inferred from the names variable.
• I suppose your code editor does not have proper autocompletion settings. I work well in my VSCode setup.

About the autocompletion settings, can you share me about this part of settings or plugins in the VSCode.

Thanks for your detailed answers.
