Script Preparation code:

var s2 = "b";
var s3 = "asfdasfasdfdsafkjahsdfjkhsdajkfhasjfhd";

Tests:

split
let temp; for (let i = 0;i < s1.length; i++) { temp = s1.split('').splice(i, 1); } for (let i = 0;i < s2.length; i++) { temp = s2.split('').splice(i, 1); } for (let i = 0;i < s3.length; i++) { temp = s3.split('').splice(i, 1); }
substr
let temp; for (let i = 0;i < s1.length; i++) { temp = s1.substring(0, i) + s1.substring(i + 1); } for (let i = 0;i < s2.length; i++) { temp = s2.substring(0, i) + s2.substring(i + 1); } for (let i = 0;i < s3.length; i++) { temp = s3.substring(0, i) + s3.substring(i + 1); }
clone with split
let temp; let stringArray = s1.split('') for (let i = 0;i < s1.length; i++) { temp = [...stringArray].splice(i, 1); } stringArray = s2.split('') for (let i = 0;i < s2.length; i++) { temp = [...stringArray].splice(i, 1); } stringArray = s3.split('') for (let i = 0;i < s3.length; i++) { temp = [...stringArray].splice(i, 1); }
