Ways to enable validation to be successful despite spaces in between words

Currently, I am in the process of validating inputs for special characters within my Angular application. One specific requirement is that the space between words should be allowed. Although I am new to regex, I am eager to learn and improve.

Below is the test scenario:

  it('should test for special character', () => {
    let format = /[ `!@#$%^&*()+\-=\[\]{};':"\\|,.<>\/?~]/;
    expect(format.test("Hello Angular")).toEqual(false);

  })

In order for the test to pass successfully, it needs to return false. Therefore, I would appreciate any guidance on how to adjust the format in a way that captures all special characters except for the underscore and the space between two words.

Your code snippet is effective

 var pattern=/[`!@#$%^&*()+\-=\[\]{};':"\\|,.<>\/?~]/g
 var str="Hello Angular js"
 re=pattern.test(str)
 console.log(re)

 var str="Hello Angular_js"
 re1=pattern.test(str)
 console.log(re1)

 var str="Hello Angular%js"
 re2=pattern.test(str)
 console.log(re2)

To enhance your regex, eliminate the space and take into consideration that the underscore will be matched even if it's not explicitly included in the pattern

[`!@#$%^&*()+\-=\[\]{};':"\\|,.<>\/?~]

This regex will detect all special characters listed, except for spaces and underscores
