Extract first 10 characters from a String using JavaScript substring()
To extract the first 10 character from a string, the syntax will be string.substring(0,10).
let str = "abcdefghijkl"
let tenChar = str.substring(0,10)
console.log(tenChar)
//abcdefghij <- FIRST 10 CHARACTER FROM THE STRINGThe extraction of the character starts with the position 0 (the position is index 0 ) and ends with 10 (the position is index 9).
Note:
- If the start position is greater then the end position, the
substring()will swap the two arguments. Example (5,1) will be swap to (1,5). - If the start or the end argument is less the 0, the will be treated as 0
