5 Easy Ways To Get First and Last Character From String Using JavaScript.

In this blog post you’ll learn how to extract the first and last characters of the string using JavaScript. We’ll see 5 different approaches to extract the first and last character from a string.

JavaScript method used:

CharAt()
slice()
substring()
substr()

With string[].

Approach 1: With CharAt() Method.

The CharAt method returns a character at a specific index position. 

See below example:

JavaScript

    let string = "Hello welcome to maketechstuff.com";
    console.log("First Charcter: ", string.charAt(0));
    console.log("Last Charcter: ", string.charAt(string.length - 1));

    // Output:
    // First Charcter:  H
    // Last Charcter:  m
  

Approach 2: With slice() Method.

Slice method returns the selected element.

See below code:

JavaScript

    let string = "Hello welcome to maketechstuff.com";
    console.log("First Charcter: ", string.slice(0, 1));
    console.log("First Charcter: ", string.slice(string.length-1));

    Output:
    // First Charcter:  H
    // Last Charcter:  m
  

Approach 3: With substring() Method.

Substring returns the characters between two index positions.

See below code.

JavaScript

    let string = "Hello welcome to maketechstuff.com";
    console.log("First Charcter: ", string.substring(0, 1));
    console.log("First Charcter: ", string.substring(string.length-1));
    
    Output:
    // First Charcter:  H
    // Last Charcter:  m
  

Approach 4: with substr() Method.

Substr method return characters start from specific index position upto defined length.

See below code.

JavaScript

    let string = "Hello welcome to maketechstuff.com";
    console.log("First Charcter: ", string.substr(0, 1));
    console.log("First Charcter: ", string.substr(-1));

    Output:
    // First Charcter:  H
    // Last Charcter:  m
  

Approach 5: with string[].

In this approach we directly extract the character with index value.

JavaScript

    let string = "Hello welcome to maketechstuff.com";
    console.log("First Charcter: ", string[0]);
    console.log("First Charcter: ", string[string.length - 1]);
    
    // Output:
    // First Charcter:  H
    // Last Charcter:  m
