This article mainly introduces how JavaScript converts an array to a CSV format. The example shows how javascript converts an array value to a csv string using the valueOf method, which is very useful, for more information about how to convert an array to a CSV format by using JavaScript, see the following example. Share it with you for your reference. The specific analysis is as follows:

The valueOf method of the array object in JavaScript can output the value of the array as a comma-separated string. the following code demonstrates how to replace the array with a comma-separated string and a vertical string.

Var fruits = ['apple', 'Peaches', 'oranges', 'mangoes']; var str = fruits. valueOf (); // output result: apple, peaches, oranges, mangoes

If you want to use a vertical line | split

var fruits = ['apple', 'peaches', 'oranges', 'mangoes'];var str = fruits.join("|");  //print str: apple|peaches|oranges|mangoes

The complete demo code is as follows:
