Mutated code is shown incorrectly about stryker-js HOT 2 CLOSED

I have tried to solve this issue by not generating code at all, instead by manually editing the original code string. However, this is quite buggy, because you don't always know the exact column which has been edited.

For example: The * in a * b has column: 1 while it's at column 3.

This issue becomes even more apparent when the code is split along multiple lines. For example: if the 'test' of an if statement which covers multiple lines has to be changed to false.

Only generating the part of the AST (using escodegen) which has actually been changed seems like an easier solution now. Shall I try this @nicojs ?

Sounds good to me.

Indeed i can see that we cannot find the exact location of the *-character in your example. Only the entire expression. Having the location of the entire expression is exactly enough for fitting in the escodegen generated piece
