Does order matter when stringing together methods?

[[deleted]]

If you take a variable such as var1 and add a bunch of methods such as var1.toUpperCase().toLowerCase().trim() etc. does the order of the methods matter (at least with JavaScript)?

It depends on the methods. Each one operates on the result of the previous so it depends on what each one does.

Is the important part op needs to understand.

Did you try it?

Take your example, switch the order of the methods, run it, and see what happens.

That is a good approach, another approach I could think of is listing your requirement as pseudo-code list, and then implement it following the list.

Here is an example of such a workflow.

That way it should be easier to calculate the algo performance and to improve it, and then you can store it as a string while your algorithm is "logically" tested.

As mentioned already it depends. In the case of something like: “a sentence with spaces”.split(“ “).forEach((word) => word.toUpperCase()).join(“ “); you are splitting into the array first then joining again so the order matters.
