I have this array of arrays:

let a = [

["i was sent", "i do"],
["i was sent", "i sent"],
["to protect you", "to find you"]

]

And I want to return this single array from it:

b = ["i was sent = i do", "i was sent = i sent", "to protect you = to find you"]

How can I do that?

I have tried to use a map like let b = a.map(s => s + ' = '); but it won't do the job?

    Does this answer your question? Merge/flatten an array of arrays Commented May 29, 2020 at 17:37
  • In your map statement, debug and check what s is. You'll find it's an array of two strings. Commented May 29, 2020 at 17:38

let a = [
  ["i was sent", "i do"],
  ["i was sent", "i sent"],
  ["to protect you", "to find you"]
]

let result = a.map(x => x.join(" = "))
console.log(result)

Assuming your inner arrays always have two elements:

let a = [

["i was sent", "i do"],
["i was sent", "i sent"],
["to protect you", "to find you"]

]

let b = a.map(el => `${el[0]} = ${el[1]}`);

console.log(b);

You could use a for loop to iterate through the array, and joining each of the 2nd dimensional arrays. You could use something like this:
for(var i = 0 ; i < array.length ; i++) { array[i] = array[i][0] + " = " + array[i][1]; }

mine...

let a = 
    [ [ "i was sent", "i do"] 
    , [ "i was sent", "i sent"] 
    , [ "to protect you", "to find you"] 
    ] 

const jojo=([x,y])=>x+' = '+y

let b = a.map(jojo)

console.log ( b )
