This article mainly introduces "what are the advantages and disadvantages of JS array traversal function". In daily operation, I believe many people have doubts about the advantages and disadvantages of JS array traversal function. Xiaobian consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubt of "what are the advantages and disadvantages of JS array traversal function?" Next, please follow the editor to study!

JS array traverses ordinary functions

Advantages: support for process control (break, continue, return)

Forconst arr = ["A", "B", "C"] for (let I = 0; I higher order function

Shortcomings, unable to carry out process control

Mapconst arr = ["A", "B", "C"] arr.map (e = > console.log (e))

Advantages: concise syntax, returning a mapping array of an old array, without affecting the original array

ForEachconst arr = ["A", "B", "C"] arr.forEach (e = > console.log (e))

Advantages: concise syntax, better performance than map when there is no need to return an array

At this point, the name flow control function forTfor ofTforEachTmapT ends the study of "what are the advantages and disadvantages of JS array traversal functions". I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
