Question : replace spaces with underscores in an array javascript
Answered by : richard-lievesley
var my_array = ['text one', 'text two', 'text three']
console.log(my_array) // Prints normally.
my_array = spacesToUnderscores(my_array)
console.log(my_array) // Now all strings have underscores instead of spaces.
function spacesToUnderscores(arr)
{ for(let i=0; i<=arr.length-1; i++) arr[i] = arr[i].replace(' ', '_') return arr
