While we're unable to utilize bitwise operators in templates, what is the rationale behind tslint prohibiting their use within TypeScript code?
"no-bitwise": true,
Linters are a valuable tool for maintaining code consistency, cleanliness, and readability. They can help catch common developer mistakes like unreachable code or unused variables, and alert you to potentially problematic coding practices that may be technically allowed.
In the information provided by the TSLint documentation
Bitwise operators are often the result of typos - for instance, using
bool1 & bool2instead ofbool1 && bool2. They can also indicate overly complex code that hinders maintainability.
Due to the frequency of these typo occurrences compared to valid bitwise operator usage, TSLint by default prohibits their use.
Unless you are specifically working on a project that necessitates bitwise operations, it is recommended to leave this rule enabled (as even you can inadvertently make such mistakes). However, if you do have a legitimate reason for using bitwise operators, you can temporarily disable the rule for that specific line or block of code like so:
/* tslint:disable:no-bitwise */
const redColor = (decimalColor & 0xff0000) >> 16;
const greenColor = (decimalColor & 0x00ff00) >> 8;
const blueColor = decimalColor & 0x0000ff;
/* tslint:enable:no-bitwise */
Just remember to re-enable the rule!
Alternatively, for a single line:
// tslint:disable-next-line:no-bitwise
const redColor = (decimalColor & 0xff0000) >> 16;
If you are using ESLint, refer to the documentation here
It is common for developers to make typos with bitwise operators, such as using & instead of &&. Using bitwise operators can also indicate overly complex code that is difficult to maintain.
After examining the Documentation
"Using bitwise operators in JavaScript is quite uncommon"
However, it is possible to deactivate the bitwise option to prevent the warnings.
