如何在数组中的字符串之间插入单词？

Question

I have such a data structure:

const array = ["item", "item1", "item2", "item4"]

items can be different number. I need to convert this data into "item" OR "item1" OR "item2" OR "item4" I used lodash join() but it gives me string "item OR item1 OR item2 OR item4" and this is not what I need. How can I receive such a structure "item" OR "item1" OR "item2" OR "item4 from an array?

Answer 1

Use join() and wrap result with extra "

 const array = ["item", "item1", "item2", "item4"] console.log('"' + array.join('" OR "') + '"')

Answer 2

map over the elements to return them as quoted strings (here using a template literal ), then join them:

 const array = ["item", "item1", "item2", "item4"]; const str = array.map(el => `"${el}"`).join(' OR '); console.log(str);

Answer 3

You could use stringify the items and join with ' OR ' .

 const array = ["item", "item1", "item2", "item4"], string = array.map(o => JSON.stringify(o)).join(' OR '); console.log(string);
